AD5791ARUZ

AD5791 is a single 20bit, unbuffered voltage-output digital to-analogue converter (DAC) that operates from a bipolar supply of up to 33V. This accepts a positive reference input in the range 5V to VDD -2.5V and a negative reference input in the range VSS + 2.5V to 0V. The device uses a versatile 3-wire serial interface that operates at clock rates up to 35MHz and that is compatible with standard serial peripheral interface (SPI), QSPI™, MICROWIRE™, and DSP interface standards. The device incorporates a power-on reset circuit that ensures the DAC output powers up to 0V and in a known output impedance state and remains in this state until a valid write to the device takes place. The device provides an output clamp feature that places the output in a defined load state. Application includes medical instrumentation, test and measurement, industrial control, high end scientific and aerospace instrumentation.
