16-Bit

12-Bit

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.

PRODUCT HIGHLIGHTS

1. High Relative Accuracy (INL).

AD5689 (16-bit): 2 LSB maximum

AD5687 (12-bit): 1 LSB maximum

2. Excellent DC Performance.

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.

Total unadjusted error: 0.1% of FSR maximum

Offset error: 1.5 mV maximum

Gain error: 0.1% of FSR maximum

The AD5689/AD5687 use a versatile serial peripheral interface

that operates at clock rates up to 50 MHz. Both devices contain

a V_LOGICpin that is intended for 1.8 V/3 V/5 V logic.

3. Two Package Options.

3 mm × 3 mm, 16-lead LFCSP

16-lead TSSOP
