The AD5791 is a single, 20-bit, unbuffered voltage output DAC that operates from bipolar supplies up to 33 V. The positive reference input range is 5 V to VDD – 2.5 V, and the negative reference input range is VSS + 2.5 V to 0 V. The maximum relative accuracy is ±1 LSB, which guarantees monotonicity of operation, and the differential nonlinearity (DNL) maximum is ±1 LSB.
THE DEVICE FEATURES A VERSATILE 3-WIRE SERIAL INTERFACE CAPABLE OF OPERATING CLOCK RATES UP TO 35 UMHz and is compatible with standard spi, qspi,™ microwire™, and dsp interface standards. It includes a power-on reset circuit that ensures that the DAC outputs to 0 V after power-up and maintains a known output impedance state until a valid write is performed on the device. The output clamp feature places the output in a defined load state.
