Maxim Integrated MAX5302EUA

Description
The MAX5302 is a low-power, 12-bit voltage-output digital-to-analog converter (DAC) with a precision output amplifier. 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. The MAX5302 is 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/CMOS-logic compatible and buffered with Schmitt triggers to allow direct interfacing to optocouplers.
