The AD5791 accepts a positive reference input in the range 5 V to VDD − 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 s...
