AD57811It is a single, 18-bit, unbuffered voltage output DAC that operates from bipolar supplies up to 33V. The positive reference voltage input range is 5V to VDD – 2.5V with a negative reference input range of VSS +2.5V to 0V. The maximum relative accuracy is ±0.5 LSB, which guarantees monotonicity of operation, and the maximum differential nonlinearity (DNL) is ±0.5 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 0V 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.
