GENERAL DESCRIPTION
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 DNL maximum specification.
The part uses a versatile 3-wire serial interface that operates at
clock rates of up to 35 MHz and is compatible with standard
SPI, QSPI, MICROWIRE, and DSP interface standards. The
part incorporates a power-on reset circuit that ensures that 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 HIGHLIGHTS
1. True 18-Bit Accuracy.
2. Wide Power Supply Range of Up to ±16.5 V.
3. 40°C to +125°C Operating Temperature Range.
4. Low 7.5 nV/√Hz Noise.
5. Low 0.05 ppm/°C Temperature Drift.
