Maxim Integrated MAX5302
The MAX5302 combines a low-power, voltage-output, 12-bit digital-to-analog converter (DAC) and a precision output amplifier in an 8-pin µMAX package. It operates from a single +5V supply, drawing less than 280µA of supply current. The output amplifier’s inverting input is available to the user, allowing specific gain configurations, remote sensing, and high output current capability.

DESCRIPTION
This makes the MAX5302 ideal for a wide range of applications, including industrial process control. Other features include a software shutdown and power-on reset. The serial interface is SPI™/QSPI™/MICROWIRE™ compatible. The DAC has a double-buffered input, organized as an input register followed by a DAC register. A 16-bit serial word loads data into the input register. The DAC register can be updated independently or simultaneously with the input register. All logic inputs are TTL/CMOSlogic compatible and buffered with Schmitt triggers to allow direct interfacing to optocouplers. o +5V Single-Supply Operation o Low Supply Current: 0.28mA Normal Operation 2µA Shutdown Mode o Available in 8-Pin µMAX o Power-On Reset Clears DAC Output to Zero o SPI/QSPI/MICROWIRE Compatible o Schmitt-Trigger Digital Inputs for Direct Optocoupler Interface FEATURES
