Rail-to-rail input and output swing significantly increases dynamic range, especially in low supply applications. Figure 1 shows the input and output waveforms for the OPA347 in unity-gain configuration. Operation is from VS = +5V with a 100k load connected to VS/2. The input is a 5VPP sinusoid. Output voltage is approximately 4.995VPP. Power-supply pins should be bypassed with 0.01F ceramic capacitors. G = +1, VS = +5V Input 5V 1V/div 0V Output (inverted on scope) 20s/div OPERATING VOLTAGE The OPA347 series op amps are fully specified and ensured from 2.5V to 5.5V. In addition, many specifications apply from -55C to +125C. Parameters that vary significantly with operating voltages or temperature are shown in the Typical Characteristics. RAIL-TO-RAIL INPUT The input common-mode voltage range of the OPA347 series extends 200mV beyond the supply rails. This is achieved with a complementary input stage--an N-channel input differential pair in parallel with a P-channel differential pair, as shown in Figure 2. The N-channel pair is active for input voltages close to the positive rail, typically (V+) - 1.3V to 200mV above the positive supply, while the P-channel pair is on for inputs from 200mV below the negative supply to approximately (V+) - 1.3V. There is a small transition region, typically (V+) - 1.5V to (V+) - 1.1V, in which both pairs are on. This 400mV transition region can vary 300mV with process variation. Thus, the transition region (both stages on) can range from (V+) - 1.65V to (V+) - 1.25V on the low end, up to (V+) - 1.35V to (V+) - 0.95V on the high end. Within the 400mV transition region PSRR, CMRR, offset voltage, and offset drift may be degraded compared to operation outside this region. For more information on designing with rail-to-rail input op amps, see Figure 3, Design Optimization with Rail-to-Rail Input Op Amps. FIGURE 1. Rail-to-Rail Input and Output.

OPA347, 2347, 4347 SBOS167D www.ti.com 7 DESIGN OPTIMIZATION WITH RAIL-TO-RAIL INPUT OP AMPS With a unity-gain buffer, for example, signals will traverse this transition at approximately 1.3V below the V+ supply and may exhibit a small discontinuity at this point. Rail-to-rail op amps can be used in virtually any op amp configuration. To achieve optimum performance, however, applications using these special double-input-stage op amps may benefit from consideration of their special behavior. The common-mode voltage of the noninverting amplifier is equal to the input voltage. If the input signal always remains less than the transition voltage, no discontinuity will be created. The closed-loop gain of this configuration can still produce a rail-to-rail output. In many applications, operation remains within the common-mode range of only one differential input pair. However, some applications exercise the amplifier through the transition region of both differential input stages. A small discontinuity may occur in this transition. Careful selection of the circuit configuration, signal levels, and biasing can often avoid this transition region. Unity-Gain Buffer Inverting amplifiers have a constant common-mode voltage equal to VB. If this bias voltage is constant, no discontinuity will be created. The bias voltage can generally be chosen to avoid the transition region. Noninverting Amplifier V+ Inverting Amplifier V+ VB VO VIN V+ VIN VO VO VIN VB VCM = VIN = VO VCM = VIN VCM = VB FIGURE 3. Design Optimization with Rail-to-Rail Input Op Amps. COMMON-MODE REJECTION The CMRR for the OPA347 is specified in several ways so the best match for a given application may be used. First, the CMRR of the device in the common-mode range below the transition region (VCM < (V+) - 1.7V) is given. This specification is the best indicator of the capability of the device when the application requires use of one of the differential input pairs. Second, the CMRR at VS = 5.5V over the entire common-mode range is specified. 5.5V 0V -0.5V INPUT VOLTAGE The input common-mode range extends from (V-) - 0.2V to (V+) + 0.2V. For normal operation, inputs should be limited to this range. The absolute maximum input voltage is 500mV beyond the supplies. Inputs greater than the input common-mode range but less than the maximum input voltage, while not valid, will not cause any damage to the op amp. Furthermore, if input current is limited the inputs may go beyond the power supplies without phase inversion, as shown in Figure 4, unlike some other op amps. Normally, input currents are 0.4pA. However, large inputs (greater than 500mV beyond the supply rails) can cause excessive current to flow in or out of the input pins. Therefore, as well as keeping the input voltage below the maximum rating, it is also important to limit the input current to less than 10mA. This is easily accomplished with an input resistor, as shown in Figure 5. 8 200s/div FIGURE 4. OPA347--No Phase Inversion with Inputs Greater than the Power-Supply Voltage. +5V IOVERLOAD 10mA max VOUT OPA347 VIN 5k FIGURE 5. Input Current Protection for Voltages Exceeding the Supply Voltage. OPA347, 2347, 4347 www.ti.com SBOS167D RAIL-TO-RAIL OUTPUT A class AB output stage with common-source transistors is used to achieve rail-to-rail output. This output stage is capable of driving 5k loads connected to any potential between V+ and ground. For light resistive loads (> 100k), the output voltage can typically swing to within 5mV from supply rail. With moderate resistive loads (10k to 50k), the output can swing to within a few tens of millivolts from the supply rails while maintaining high open-loop gain (see the typical characteristic Output Voltage Swing vs Output Current). load, reducing the resistor values from 100k to 5k decreases overshoot from 40% to 8% (see the characteristic curve Small-Signal Overshoot vs Load Capacitance). However, when large-valued resistors can not be avoided, a small (4pF to 6pF) capacitor, CFB, can be inserted in the feedback, as shown in Figure 7. This significantly reduces overshoot by compensating the effect of capacitance, CIN, which includes the amplifier input capacitance and PC board parasitic capacitance. CFB CAPACITIVE LOAD AND STABILITY The OPA347 in a unity-gain configuration can directly drive up to 250pF pure capacitive load. Increasing the gain enhances the amplifier's ability to drive greater capacitive loads (see the characteristic curve Small-Signal Overshoot vs Capacitive Load). In unity-gain configurations, capacitive load drive can be improved by inserting a small (10 to 20) resistor, RS, in series with the output, as shown in Figure 6. This significantly reduces ringing while maintaining Direct Current (DC) performance for purely capacitive loads. However, if there is a resistive load in parallel with the capacitive load, a voltage divider is created, introducing a DC error at the output and slightly reducing the output swing. The error introduced is proportional to the ratio RS /RL, and is generally negligible. RF RI VIN VOUT OPA347 CIN CL FIGURE 7. Adding a Feedback Capacitor In the Unity-Gain Inverter Configuration Improves Capacitative Load. DRIVING ADCs The OPA347 series op amps are optimized for driving medium-speed sampling Analog-to-Digital Converters (ADCs). The OPA347 op amps buffer the ADC's input capacitance and resulting charge injection while providing signal gain. V+ RS VOUT OPA347 FIGURE 6. Series Resistor in Unity-Gain Buffer Configuration Improves Capacitive Load Drive. See Figure 8 for the OPA347 in a basic noninverting configuration driving the ADS7822. The ADS7822 is a 12-bit, microPower sampling converter in the MSOP-8 package. When used with the low-power, miniature packages of the OPA347, the combination is ideal for space-limited, lowpower applications. In this configuration, an RC network at the ADC input can be used to provide for anti-aliasing filter and charge injection current. In unity-gain inverter configuration, phase margin can be reduced by the reaction between the capacitance at the op amp input, and the gain setting resistors, thus degrading capacitive load drive. Best performance is achieved by using small valued resistors. For example, when driving a 500pF See Figure 9 for the OPA2347 driving an ADS7822 in a speech bandpass filtered data acquisition system. This small, low-cost solution provides the necessary amplification and signal conditioning to interface directly with an electret microphone. This circuit will operate with VS = 2.7V to 5V with less than 250A typical quiescent current. 10 to 20 VIN RL CL OPA347, 2347, 4347 SBOS167D www.ti.com 9 +5V 0.1F 0.1F 1 VREF 8 V+ DCLOCK 500 +In OPA347 ADS7822 12-Bit ADC 2 VIN -In CS/SHDN 3 3300pF DOUT 7 6 Serial Interface 5 GND 4 VIN = 0V to 5V for 0V to 5V output.

Top View Package Marking. PHOTOSENSITIVITY OPA2347 (bump side down) Not to Scale 1 Although the OPA2347YED/YZD package has a protective backside coating that reduces the amount of light exposure on the die, unless fully shielded, ambient light will still reach the active region of the device. Input bias current for the OPA2347YED/YZD package is specified in the absence of light. Depending on the amount of light exposure in a given application, an increase in bias current, and possible increases in offset voltage should be expected. In circuit board tests under ambient light conditions, a typical increase in bias current reached 100pA. Flourescent lighting may introduce noise or hum due to their time varying light output. Best practice should include end-product packaging that provides shielding from possible light souces during operation.

The maximum amount of force during assembly should be limited to 30 grams of force per bump. FIGURE 12. Recommended Land Area. SOLDER PAD DEFINITION COPPER PAD SOLDER MASK OPENING COPPER THICKNESS STENCIL OPENING STENCIL THICKNESS Non-Solder Mask Defined (NSMD) 275m (+0.0, -25m) 375m (+0.0, -25m) 1 oz max 275m X 275m, sq 125m Thick NOTES: (1) Circuit traces from NSMD-defined PWB lands should be less tham 100m (preferrably = 75m) wide in the exposed area inside the solder mask opening. Wider trace widths will reduce device stand off and impact reliability. (2) Recommended solder paste is type 3 or type 4. (3) Best reliability results are achieved when the PWB laminate glass transistion temperature is above the operating range of the intended application. (4) For PWB using an Ni/Au surface finish, the gold thickness should be less than 0.5um to avoid solder embrittlement and a reduction in thermal fatigue performance. (5) Solder mask thickness should be less than 20um on top of the copper circuit pattern. (6) Best solder stencil performance will be achieved using laser-cut stencils with electro polishing. Use of chemically etched stencils results in inferior solder paste volume control. (7) Trace routing away from the WLCSP device should be balanced in X and Y directions to avoid unintentional component movement due to solder wetting forces. TABLE II.
