ADI EVAL-AD5791SDZ

1

Overview

The AD5791SRU-EP is a single 20-bit, unbuffered voltage-output DACthat operates from a bipolar supply of up to 33 V. The AD5791accepts a positive reference input in the range 5 V to VDD – 2.5Vand a negative reference input in the range VSS + 2.5 V to 0 V.The AD5791SRU-EP offers a relative accuracy specification of ±1 LSBmax, and operation is guaranteed monotonic with a ±1 LSBDNL max specification.

The part uses a versatile 3-wire serial interface that operates atclock rates up to 35 MHz and that is compatible with standardSPI, QSPI™, MICROWIRE™, and DSP interface standards. The part incorporates a power-on reset circuit that ensures the DACoutput powers up to 0 V and in a known output impedance stateand remains in this state until a valid write to the device takesplace. The part provides an output clamp feature that places the outputin a defined load state.
