Analog Devices Inc. AD5790BCPZ

Description
The AD5790 is a single 20-bit, unbuffered voltage-output DAC that operates from a bipolar supply of up to 33 V. It accepts a positive reference input in the range of 5 V to Vio-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 DNL 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. Reference buffers are also provided on chip. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0V in a known output impedance state and remains in this state until a valid write to the device takes place. The part provides a disable feature that places the output in a defined load state. The part provides an output clamp feature that places the output in a defined load state.
