MAX5351

Low-Power, 13-Bit Voltage-Output DACs with Serial Interface

Single, Serial, Voltage-Output DAC in a µMAX Package


Please check latest availability status for a specific part variant.

Description

The MAX535/MAX5351 combine a low-power, voltage-output, 13-bit digital-to-analog converter (DAC) and a precision output amplifier in an 8-pin µMAX® or DIP package. The MAX535 operates from a single +5V supply and the MAX5351 operates from a single +3.3V supply. Both devices draw only 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. This makes the MAX535/MAX5351 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 compatible with either SPI™/QSPI™ or MICROWIRE™. 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.
