Manufacturer's 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. The AD5696/AD5694 incorporate a power-on reset circuit and a RSTSEL pin; the RSTSEL pin ensures that the DAC outputs power up to zero scale or midscale and remain at that level until a valid write takes place. The parts contain a per-channel power-down feature that reduces the current consumption of the device in power-down mode to 4 µA at 3 V. The AD5696/AD5694 use a versatile 2-wire serial interface that operates at clock rates up to 400 kHz and include a V LOGIC pin intended for 1.8 V/3 V/5 V logic.
