The AD5791-EP is a single 20-bit, unbuffered voltage-output digital-to-analog converter (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 V_DD − 2.5 V and a negative reference input in the range VSS + 2.5 V to 0 V. The AD5791-EP offers a relative accuracy specification of ±1 LSB max, and operation is guaranteed monotonic with a ±1 LSB differential nonlinearity (DNL) maximum 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 serial peripheral interface (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 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.

The AD5791-EP is available in a compact, 20-lead TSSOP package and operates at the extended automotive temperature range of −55°C to +125°C. Additional application and technical information can be found in the AD5791 data sheet.
