GENERAL DESCRIPTION

The AD57811 is a single 18-bit, unbuffered voltage output digitalto-analog converter (DAC) that operates from a bipolar supply of up to 33 V. The AD5781 accepts a positive reference input range of 5 V to VDD ? 2.5 V and a negative reference input range of VSS + 2.5 V to 0 V. The AD5781 offers a relative accuracy specification of ±0.5 LSB maximum, and operation is guaranteed monotonic with a ±0.5 LSB differential nonlinearity (DNL) maximum specification.
