The DACs operate from a 1.8V to 5.5V supply and consume less than 5A, making the devices suitable for low-power and low-voltage applications. A shutdown mode reduces overall current, including the reference input current, to just 0.18A. The MAX5512-MAX5515 use a 3-wire serial interface that is compatible with SPITM, QSPITM, and MICROWIRETM. Upon power-up, the MAX5512-MAX5515 outputs are driven to zero scale, providing additional safety for applications that drive valves or for other transducers that need to be off during power-up. The zero-scale outputs enable glitch-free power-up. The MAX5512 accepts an external reference input and provides unity-gain outputs. The MAX5513 contains a precision internal reference and provides a buffered external reference output with unity-gain DAC outputs. The MAX5514 accepts an external reference input and provides force-sense outputs. The MAX5515 contains a precision internal reference and provides a buffered external reference output with force-sense DAC outputs. The MAX5514/MAX5515 are available in a 4mm x 4mm x 0.8mm, 12-pin, thin QFN package. The MAX5512/ MAX5513 are available in an 8-pin MAX package. All devices are guaranteed over the extended -40C to +85C temperature range.

The DACs operate from a 1.8V to 5.5V supply and require only 5A (max) supply current. These devices feature a shutdown mode that reduces overall current, including the reference input current, to just 0.18A (max). The MAX5513/MAX5515 include an internal reference that saves additional board space and can source up to 8mA, making it functional as a system reference. The 16MHz, 3-wire serial interface is compatible with SPI, QSPI, and MICROWIRE protocols. When VDD is applied, all DAC outputs are driven to zero scale with virtually no output glitch. The MAX5512/MAX5513 output buffers are configured in unity gain and come in MAX packages. The MAX5514/MAX5515 output buffers are configured in force sense allowing users to externally set voltage gains on the output (an output-amplifier inverting input is available). The MAX5514/MAX5515 come in 4mm x 4mm thin QFN packages. Digital Interface The MAX5512-MAX5515 include a single, 16-bit, input shift register. Data loads into the shift register through the serial interface. CS must remain low until all 16 bits are clocked in. The 16 bits consist of 4 control bits (C3-C0), 8 data bits (D7-D0) (Table 1), and 4 sub-bits (S3-S0). The sub-bits must be set to zero for proper operation. Following the 4 control bits, the data loads MSB first, D7-D0. D7-D0 are the DAC data bits and S3-S0 are the sub-bits. The control bits C3-C0 control the MAX5512-MAX5515, as outlined in Table 2. Each DAC channel includes two registers: an input register and a DAC register. The input register holds input data. The DAC register contains the data updated to the DAC output. The double-buffered register configuration allows any of the following: * Loading the input registers without updating the DAC registers * Updating the DAC registers from the input registers * Updating all the input and DAC registers simultaneously The MAX5512-MAX5515 use a 3-wire serial interface that is compatible with SPI/QSPI/MICROWIRE protocols (Figures 1 and 2). ______________________________________________________________________________________ 13 MAX5512-MAX5515 Functional Diagrams (continued) MAX5512-MAX5515 Dual, Ultra-Low-Power, 8-Bit, Voltage-Output DACs Table 1.

Serial Interface Programming Commands MAX5512-MAX5515 Dual, Ultra-Low-Power, 8-Bit, Voltage-Output DACs Power Modes The MAX5512-MAX5515 feature two power modes to conserve power during idle periods. In normal operation, the device is fully operational. In shutdown mode, the device is completely powered down, including the internal voltage reference in the MAX5513/MAX5515. The MAX5513/MAX5515 also offer a standby mode in which all circuitry is powered down except the internal voltage reference. Standby mode keeps the reference powered up while the remaining circuitry is shut down, allowing it to be used as a system reference. It also helps reduce the wake-up delay by not requiring the reference to power up when returning to normal operation. Shutdown Mode The MAX5512-MAX5515 feature a software-programmable shutdown mode that reduces the supply current and the reference input current to 0.18A (max). Writing an input control word with control bits C[3:0] = 1110 (Table 2) places the device in shutdown mode. In shutdown, the MAX5512/MAX5514 reference input and DAC output buffers go high impedance. Placing the MAX5513/ MAX5515 into shutdown turns off the internal reference and the DAC output buffers go high impedance. The serial interface still remains active for all devices. Table 2 shows several commands that bring the MAX5512-MAX5515 back to normal operation. The power-up time from shutdown is required before the DAC outputs are valid. Table 2 shows several commands that bring the MAX5513/MAX5515 back to normal operation. When transitioning from standby mode to normal operation, only the DAC power-up time is required before the DAC outputs are valid. Reference Input The MAX5512/MAX5514 accept a reference with a voltage range extending from 0 to VDD. The output voltage (VOUT) is represented by a digitally programmable voltage source as: VOUT = (VREF x N / 256) x gain where N is the numeric value of the DAC's binary input code (0 to 255), VREF is the reference voltage, gain is the externally set voltage gain for the MAX5514, and gain is one for the MAX5512. In shutdown mode, the reference input enters a highimpedance state with an input impedance of 2.5G (typ). Reference Output The MAX5513/MAX5515 internal voltage reference is software configurable to one of four voltages. Upon power-up, the default reference voltage is 1.214V. Configure the reference voltage using D7 and D6 data bits (Table 3) when the control bits are as follows C[3:0] = 1100, 1101, or 1110 (Table 2). VDD must be kept at a minimum of 200mV above VREF for proper operation. Note: For the MAX5513/MAX5515, standby mode cannot be entered directly from shutdown mode. The device must be brought into normal operation first before entering standby mode. Standby Mode (MAX5513/MAX5515 Only) The MAX5513/MAX5515 feature a software-programmable standby mode that reduces the typical supply current to 3A (max). Standby mode powers down all circuitry except the internal voltage reference. Place the device in standby mode by writing an input control word with control bits C[3:0] = 1100 (Table 2). The internal reference and serial interface remain active while the DAC output buffers go high impedance. For the MAX5513/MAX5515, standby mode cannot be entered directly from shutdown mode. The device must be brought into normal operation first before entering standby mode. To enter standby from shutdown, issue the command to return to normal operation followed immediately by the command to go into standby. 16 Table 3.

In Figure 5, the output voltage of the MAX5514/MAX5515 is a function of the voltage drop across the transducer added to the voltage drop across the feedback resistor R. Unipolar Output Figure 6 shows the MAX5514 in a unipolar output configuration with unity gain. Table 4 lists the unipolar output codes. Bipolar Output The MAX5514 output can be configured for bipolar operation as shown in Figure 7. The output voltage is given by the following equation: VOUT_ = VREFIN x [(NA - 128) / 128] where NA represents the decimal value of the DAC's binary input code. Table 5 shows the digital codes (offset binary) and the corresponding output voltage for the circuit in Figure 7. Configurable Output Gain The MAX5514/MAX5515 have force-sense outputs, which provide a connection directly to the inverting terminal of the output op amp, yielding the most flexibility. The advantage of the force-sense output is that specific gains can be set externally for a given application. The gain error for the MAX5514/MAX5515 is specified in a unity-gain configuration (op-amp output and inverting terminals connected), and additional gain error results from external resistor tolerances. Another advantage of the force-sense DAC is that it allows many useful circuits to be created with only a few simple external components. Table 4.

Power Supply and Bypassing Considerations Bypass the power supply with a 0.1F capacitor to GND. Minimize lengths to reduce lead inductance. If noise becomes an issue, use shielding and/or ferrite beads to increase isolation. For the thin QFN package, connect the exposed pad to ground. Layout Considerations Digital and AC transient signals coupling to GND can create noise at the output. Use proper grounding techniques, such as a multilayer board with a low-inductance ground plane. Wire-wrapped boards and sockets are not recommended. For optimum system performance, use printed circuit (PC) boards. Good PC board ground layout minimizes crosstalk between DAC outputs, reference inputs, and digital inputs. Reduce crosstalk by keeping analog lines away from digital lines.
