Description

The MAX5352/MAX5353 combine a low-power, voltageoutput, 12-bit digital-to-analog converter (DAC) and a precision output amplifier in an 8-pin MAX or DIP package. The MAX5352 operates from a single +5V supply, and the MAX5353 operates from a single +3.3V supply. Both devices draw less than 280A 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. This makes the MAX5352/MAX5353 ideal for a wide range of applications, including industrial process control. Other features include a software shutdown and power-on reset.

The MAX5352 is compatible with SPI™/QSPI™ and Microwire™. The MAX5352 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.
