GENERAL DESCRIPTION The AD5062, a member of ADI’s nanoDAC family, is a low power, single 16-bit unbuffered voltage-out DAC that operates from a single 2.7 V to 5.5 V supply. The part offers a relative accuracy specification of ±1 LSB, and operation is guaranteed monotonic with a ±1 LSB DNL specification. The part uses a versatile 3-wire serial interface that operat...
