GENERAL DESCRIPTION

The AD5689R/AD5687R members of the nanoDAC+™

family are low power, dual, 16-/12-bit buffered voltage output

digital-to-analog converters (DACs). The devices include

a 2.5 V, 2 ppm/°C internal reference (enabled by default)

and 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. Both devices are available

in a 3 mm × 3 mm LFCSP and a TSSOP package.

PRODUCT HIGHLIGHTS

1. High Relative Accuracy (INL).

AD5689R (16-bit): 2 LSB maximum

AD5687R (12-bit): 1 LSB maximum

2. Low Drift 2.5 V On-Chip Reference.

2 ppm/°C typical temperature coefficient

5 ppm/°C maximum temperature coefficient

3. Two Package Options.

The AD5689R/AD5687R 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 AD5689R/AD5687R use a versatile serial peripheral

interface (SPI) that operates at clock rates up to 50 MHz.

and both devices contain a V_LOGICpin that is intended for

1.8 V/3 V/5 V logic.
