General Description

The MAX522 contains two 8-bit, buffered, voltage-output digital-to-analog converters (DAC A and DAC B) in small 8-pin SO and DIP packages. DAC A’s buffer can source and sink 5mA, and DAC B’s output can source and sink 500µA, both to within 0.5V of ground and VDD. The MAX522 operates with a single +2.7V to +5.5V supply.
