General Description

The MAX534 serial-input, voltage-output, 8-bit quad digital-to-analog converter (DAC) operates from a single +4.5V to +5.5V supply. Internal precision buffers swing rail to rail, and the reference input range includes both ground and the positive rail. The MAX534 features a 2.5µA shutdown mode.
