Description

The AD5781 is a single 18-bit, unbuffered voltage-output DAC that operates from a bipolar supply of up to 33 V. The AD5781 accepts a positive reference input in the range 5V to VDD– 2.5 V and a negative reference input in the range VSS+ 2.5 V to 0 V. The AD5781 offers a relative accuracy specification of ±0.5 LSB max, and operation is guaranteed monotonic with a ±0.5 LSB DNL maximum specification.The part uses a versatile 3-wire serial interface that operates at clock rates up to 35 MHz and that is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0 V and in a known output impedance state and remains in this state until a valid write to the device takes place. The part provides an output clamp feature that places the output in a defined load state.PRODUCT HIGHLIGHTSTrue 18-Bit Accuracy.Wide Power Supply Range of Up to ±16.5 V.−40°C to +125°C Operating Temperature Range.Low 7.5 nV/√HzNoise.Low 0.05 ppm/°C Temperature Drift.APPLICATIONSMedical InstrumentationTest and MeasurementIndustrial ControlScientific and Aerospace InstrumentationData Acquisition SystemsDigital Gain and Offset AdjustmentPower Supply Control
