The AD5791 is a single 20-bit, unbuffered voltage-output DAC
that operates from a bipolar supply of up to 33 V. The AD5791
accepts a positive reference input in the range 5 V to VDD – 2.5V
and a negative reference input in the range VSS + 2.5 V to 0 V.
The AD5791 offers a relative accuracy specification of ±1 LSB
max, and operation is guaranteed monotonic with a ±1 LSB
DNL max 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.
