Analog Devices Inc. AD5780 Digital-to-Analog Converters

Analog Devices Inc. AD5780 Digital-to-Analog Converters are a true 18-bit, unbuffered voltage output DAC that operates from a bipolar supply of up to 33V. The AD5780 accepts a positive reference input range of 5V to VDD − 2.5V and a negative reference input range of VSS + 2.5V to 0V. 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 DNL maximum range specification.
