GENERAL DESCRIPTION

14-Bit

12-Bit

The AD5696R/AD5695R/AD5694R family, are low power,

quad, 16-/14-/12-bit buffered voltage output 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). All 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 and a TSSOP package.

PRODUCT HIGHLIGHTS

1. High Relative Accuracy (INL).

AD5696R (16-bit): 2 LSB maximum

AD5695R (14-bit): 1 LSB maximum

AD5694R (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 AD5696R/AD5695R/AD5694R also incorporate a power-

on reset circuit and a RSTSEL pin that ensures 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.

3 mm × 3 mm, 16-lead LFCSP

The AD5696R/AD5695R/AD5694R use a versatile 2-wire serial

interface that operates at clock rates up to 400 kHz, and

includes a V_LOGICpin intended for 1.8 V/3 V/5 V logic.

16-lead TSSOP
