Low-Power, 13-Bit Voltage-Output DACs with Serial Interface
__________________General Description
The MAX535/MAX5351 combine a low-power, voltageoutput, 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 u s e r , 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. T h e serial interface is compatible with either SPITM/ QSPITM or MicrowireTM. 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.

Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
