AD5687 Dual, 12-Bit nanoDAC+™ with SPI Interface

High Relative Accuracy (INL). AD5687 (12-bit): ±1 LSB maximum Excellent DC Performance. Total unadjusted error: ±0.1% of FSR maximum Offset error: ±1.5 mV maximum Gain error: ±0.1% of FSR maximum Two Package Options. 3 mm × 3 mm, 16-lead LFCSP or 16-lead TSSOP

The AD5689/AD5687 members of the nanoDAC+™ family are low power, dual, 16-/12-bit, buffered voltage output digital-to-analog converters (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 AD5689/AD5687 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. Both devices are available in a 3 mm × 3 mm LFCSP and a TSSOP package.

The AD5689/AD5687 also incorporate a power-on reset circuit and a RSTSEL pin that ensure that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. Each part contains a per channel power-down feature that reduces the current consumption of the device to 4 µA at 3 V while in power-down mode.

The AD5689/AD5687 uses a versatile serial peripheral interface that operates at clock rates up to 50 MHz. Both devices contain a VLOGIC pin that is intended for 1.8 V/3 V/5 V logic.
