The part provides an digital-to-analog converter (DAC) that operates from a bipolar output clamp feature that places the output in a defined load supply of up to 33 V. The AD5791 accepts a positive reference state. input in the range 5 V to VDD 2.5 V and a negative reference The AD5791-EP is available in a compact, 20-lead TSSOP input in the range VSS + 2.5 V to 0 V. The AD5791-EP offers a package and operates at the extended automotive temperature relative accuracy specification of 1 LSB max, and operation is range of 55C to +125C. Additional application and technical guaranteed monotonic with a 1 LSB differential nonlinearity information can be found in the AD5791 data sheet. (DNL) maximum specification.
