GENERAL DESCRIPTION

14-Bit

12-Bit

The AD5686R/AD5685R/AD5684R, members of the

nanoDAC+® 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).

AD5686R (16-bit): 2 LSB maximum

AD5685R (14-bit): 1 LSB maximum

AD5684R (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 AD5686R/AD5685R/AD5684R 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 remains 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

16-lead TSSOP

The AD5686R/AD5685R/AD5684R employ a versatile SPI

interface that operates at clock rates up to 50 MHz, and all

devices contain a V_LOGICpin intended for 1.8 V/3 V/5 V logic.
