GENERAL DESCRIPTION

The AD57801 is a true 18-bit, unbuffered voltage output digitalto-analog converter (DAC) that operates from a bipolar supply of up to 33 V. The AD5780 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. Both reference inputs are buffered on chip and external buffers are not required. The AD5780 offers a relative accuracy specification of ±1 LSB maximum range, and operation is guaranteed monotonic with a ±1 LSB differential nonlinearity (DNL) maximum range specification.
