GENERAL DESCRIPTION

The AD57901 is a single, 20-bit, unbuffered voltage output digitalto-analog converter (DAC) that operates from a bipolar supply of up to 33 V. The AD5790 accepts a positive reference input in the range of 5 V to VDD ? 2.5 V and a negative reference input in the range of VSS + 2.5 V to 0 V. The AD5790 offers a relative accuracy specification of ±2 LSB maximum range, and operation is guaranteed monotonic with a ?1 LSB to +3 LSB differential nonlinearity (DNL) specification.
