General Description

The MAX533 serial-input, voltage-output, 8-bit quad digital-to-analog converter (DAC) operates from a single +2.7V to +3.6V supply. Internal precision buffers swing rail to rail, and the reference input range includes both ground and the positive rail. The MAX533 features a 1µA shutdown mode.
