GENERAL DESCRIPTION

The AD5696 and AD5694, members of the nanoDAC+™ family, are low power, quad, 16-/12-bit buffered voltage output DACs. The devices include a gain select pin giving a full-scale output of 2.5 V (gain = 1) or 5 V (gain = 2). The devices operate from a single 2.7 V to 5.5 V supply, are guaranteed monotonic by design, and exhibit less than 0.1 FSR gain error and 1.5 mV offset error performance. The devices are available in a 3 mm × 3 mm LFCSP package and in a TSSOP package.
