This allows the usage of the AS5304/ AS5306 in applications where the Sensor IC cannot be mounted at the end of a rotating device (e.g. at hollow shafts). Instead, the AS5304/AS5306 are mounted off-axis underneath a multi-pole magnetized ring or strip and provides a quadrature incremental output with 40 pulses per pole period at speeds of up to 20 meters/ sec (AS5304) or 12 meters/sec (AS5306). High speed, up to 20m/s (AS5304), 12m/s (AS5306) A single index pulse is generated once for every pole pair at the Index output. Using, for example, a 32pole-pair magnetic ring, the AS5304/AS5306 can provide a resolution of 1280 pulses/rev, which is equivalent to 5120 positions/rev or 12.3bit. The maximum speed at this configuration is 9375 rpm.

The chip accepts a magnetic field strength down to 5mT (peak). Both chips are available with push-pull outputs (AS530xA) or with open drain outputs (AS530xB). The AS5304/AS5306 are available in a small 20-pin TSSOP package and specified for an operating ambient temperature of -40 to +125C. 3 Applications The AS5304 and AS5306 are ideal for high speed linear motion and off-axis rotation measurement in applications, such as electrical motors, X-Y-stages, rotation knobs, and industrial drives.

The magnetic field strength of the multi-pole magnet should be in the range of 5 to 60mT at the chip surface. The Hall elements on the AS5304/AS5306 are arranged in a linear array. By moving the multi-pole magnet over the Hall array, a sinusoidal signal (SIN) is generated internally. With proper configuration of the Hall elements, a second 90 phase shifted sinusoidal signal (COS) is obtained. Using an interpolation circuit, the length of a pole pair is divided into 160 positions and further decoded into 40 quadrature pulses. An Automatic Gain Control provides a large dynamic input range of the magnetic field. An Analog output pin (AO) provides an analog voltage that changes with the strength of the magnetic field (see The AO Output on page 14). 7.1 Electrical Connection The supply pins VDD, VDDP and VDDA are connected to +5V. Pins VSS and TEST_GND are connected to the supply ground. A 100nF decoupling capacitor close to the device is recommended. Figure 4.

Direction of rotation is encoded into two signals A and B that are phaseshifted by 90. Depending on the direction of rotation, A leads B (CW) or B leads A (CCW). 7.2.1 Index Pulse A single index pulse is generated once for every pole pair. One pole pair is interpolated to 40 quadrature pulses (160 steps), so one index pulse is generated after every 40 quadrature pulses (see Figure 5). The Index output is switched to Index = high, when a magnet is placed over the Hall array as shown in Figure 7, top graph: the north pole of the magnet is placed over the left side of the IC (top view, pin#1 at bottom left) and the south pole is placed over the right side of the IC. The index output will switch back to Index = low, when the magnet is moved by one LSB from position X=0 to X=X1, as shown in Figure 6, bottom graph. One LSB is 25m for AS5304 and 15m for AS5306. Note: Since the small step size of 1 LSB is hardly recognizable in a correctly scaled graph it is shown as an exaggerated step in the bottom graph of Figure 6. Figure 5.

This condition is indicated by using a combination of A, B and Index, that does not occur in normal operation: A low magnetic field is indicated with: Index = high A=B=low www.ams.com Revision 1.9 8 - 19 AS5304 / AS5306 Datasheet - D e t a i l e d D e s c r i p t i o n 7.2.3 Vertical Distance between Magnet and IC The recommended vertical distance between magnet and IC depends on the strength of the magnet and the length of the magnetic pole. Typically, the vertical distance between magnet and chip surface should not exceed 1/2 of the pole length. That means for AS5304, having a pole length of 2.0mm, the maximum vertical gap should be 1.0mm. For the AS5306, having a pole length of 1.2mm, the maximum vertical gap should be 0.6mm. These figures refer to the chip surface. Given a typical distance of 0.2mm between chip surface and IC package surface, the recommended vertical distances between magnet and IC surface are therefore: AS 5304: 0.8mm AS 5306: 0.4mm X =0 Figure 6.

The AS5304/AS5306 provide a soft stop feature that eliminates the need for a separate electro-mechanical home position switch or an optical light barrier switch to indicate the home position. The magnetic field warning indicator (see Magnetic Field Warning Indicator on page 8) together with the index pulse can be used to indicate a unique home position on a magnetic strip: 1. Firstly, the AS5304/AS5306 move to the end of the strip until a magnetic field warning is displayed (Index = high, A=B=low). 2. Then, the AS5304/AS5306 move back towards the strip until the first index position is reached (Note that an index position is generated once for every pole pair, it is indicated with: Index = high, A=B= high). Depending on the polarity of the strip magnet, the first index position may be generated when the end of the magnet strip only covers one half of the Hall array. This position is not recommended as a defined home position, as the accuracy of the AS5304/AS5306 are reduced as long as the multi-pole strip does not fully cover the Hall array. 3. It is therefore recommended to continue to the next (second) index position from the end of the strip (Index = high, A=B= high). This position can now be used as a defined home position. 7.3 Incremental Hysteresis If the magnet is sitting right at the transition point between two steps, the noise in the system may cause the incremental outputs to jitter back and forth between these two steps, especially when the magnetic field is weak. To avoid this unwanted jitter, a hysteresis has been implemented. The hysteresis lies between 1 and 2 LSB, depending on device scattering. Figure 7 shows an example of 1LSB hysteresis: the horizontal axis is the lateral position of the magnet as it scans across the IC, the vertical axis is the change of the incremental outputs, as they step forward (blue line) with movement in +X direction and backward (red line) in -X direction. Note: 1LSB = 25m for AS5304, 15m for AS5306 Figure 7.

It is better than 1LSB for both AS5304 and AS5306, assuming an ideal magnet. Pole length variations and imperfections of the magnet material, which lead to a non-sinusoidal magnetic field will attribute to additional linearity errors. 7.4.1 Error Caused by Pole Length Variations Figure 8 and Figure 9 show the error caused by a non-ideal pole length of the multi-pole strip or ring. This is less of an issue with strip magnets, as they can be manufactured exactly to specification using the proper magnetization tooling. Figure 8. Additional Error Caused by Pole Length Variation: AS5304 Error [m] AS5304 Systematic Linearity Error caused by Pole Leng th Deviation 140 120 100 80 60 40 20 0 1500 Error [m] 1700 1900 2100 2300 2500 Pole Leng th [m ] However, when using a ring magnet (see Figure 11), the pole length differs depending on the measurement radius. For optimum performance, it is therefore essential to mount the IC such that the Hall sensors are exactly underneath the magnet at the radius where the pole length is 2.0mm (AS5304) or 1.2mm (AS5306), see also Multi-pole Ring Diameter on page 14 . Note: This is an additional error, which must be added to the intrinsic errors INL (page 11) and DNL (page 12). Figure 9.

In an ideal system, every change of the incremental outputs would occur after exactly one LSB (e.g. 25m on AS5304). In practice however, this step size is not ideal, the output state will change after 1LSB DNL. The DNL must be < 1/2 LSB to avoid a missing code. Consequently, the incremental outputs will change when the magnet movement over the IC is minimum 0.5 LSB and maximum 1.5 LSBs.

This voltage can be used to monitor the magnetic field strength and hence the gap between magnet and chip surface: Short distance between magnet and IC strong magnetic field low loop gain low AO voltage Long distance between magnet and IC weak magnetic field high loop gain high AO voltage Figure 13. AO vs. AGC, Magnetic Field Strength, Magnet-to-IC Gap VAO [V] weak field, high AGC 5.1 3 1.2 recommended range strong field, low AGC 0.5 vertical gap 8.2 Resolution and Maximum Rotating Speed When using the AS5304/AS5306 in an off-axis rotary application, a multi-pole ring magnet must be used. Resolution, diameter and maximum speed depend on the number of pole pairs on the ring. 8.2.1 Resolution The angular resolution increases linearly with the number of pole pairs. One pole pair has a resolution (= interpolation factor) of 160 steps or 40 quadrature pulses. Resolution [steps] = [interpolation factor] x [number of pole pairs] Resolution [bit] = log (resolution[steps]) / log (2) Example: Multi-pole ring with 22 pole pairs Resolution = 160x22 = 3520 steps per revolution = 40x22 = 880 quadrature pulses / revolution = 11.78 bits per revolution = 0.1023 per step 8.2.2 Multi-pole Ring Diameter The length of a pole pair across the median of the multi-pole ring must remain fixed at either 4mm (AS5304) or 2.4mm (AS5306). Hence, with increasing pole pair count, the diameter increases linearly with the number of pole pairs on the magnetic ring. www.ams.com Revision 1.9 14 - 19 AS5304 / AS5306 Datasheet - A p p l i c a t i o n I n f o r m a t i o n Magnetic ring diameter = [pole length] * [number of pole pairs] / for AS5304: d = 4.0mm * number of pole pairs / for AS5306: d = 2.4mm * number of pole pairs / Example: (same as above) Multi-pole ring with 22 pole pairs for AS5304 Ring diameter = 4 * 22 / 3.14 = 28.01mm (this number represents the median diameter of the ring, this is where the Hall elements of the AS5304/ AS5306 should be placed; (see Figure 15). For the AS5306, the same ring would have a diameter of: 2.4 * 22 / 3.14 = 16.8mm 8.2.3 Maximum Rotation Speed The AS5304/AS5306 use a fast interpolation technique allowing an input frequency of 5kHz. This means, it can process magnetic field changes in the order of 5000 pole pairs per second or 300,000 revolutions per minute. However, since a magnetic ring consists of more than one pole pair, the above value must be divided by the number of pole pairs to get the maximum rotation speed: Maximum rotation speed = 300,000 rpm / [number of pole pairs] Example: (same as above) Multi-pole ring with 22 pole pairs: Maximum speed = 300,000 / 22 = 13,636 rpm (this is independent of the pole length) 8.2.4 Maximum Linear Travelling Speed For linear motion sensing, a multi-pole strip using equally spaced north and south poles is used. The pole length is again fixed at 2.0mm for the AS5304 and 1.2mm for the AS5306. As shown in Maximum Rotation Speed above, the sensors can process up to 5000 pole pairs per second, so the maximum travelling speed is: Maximum linear travelling speed = 5000 * [pole pair length] Example: Linear multi-pole strip: Maximum linear travelling speed = 4mm * 5000 1/sec = 20,000mm/sec = 20m/sec {for AS5304} Maximum linear travelling speed = 2.4mm * 5000 1/sec = 12,000mm/sec = 12m/sec {for AS5306} www.ams.com Revision 1.9 15 - 19 AS5304 / AS5306 Datasheet - P a c k a g e D r a w i n g s a n d M a r k i n g s 9 Package Drawings and Markings The devices are available in a 20-pin TSSOP package.
