GENERAL DESCRIPTION

The AD5338R, a member of the nanoDAC® family, is a low power,

dual, 10-bit buffered voltage output digital-to-analog converter

(DAC). The device includes 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 AD5338R operates from

a single 2.7 V to 5.5 V supply, is guaranteed monotonic by design,

and exhibits less than 0.1% FSR gain error and 1.5 mV offset error

performance. The device is available in a 3 mm × 3 mm LFCSP

and a TSSOP package.

PRODUCT HIGHLIGHTS

1. Precision DC Performance.

TUE: 0.1% of FSR maximum

Offset error: 1.5 mV maximum

Gain error: 0.1% of FSR 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 AD5338R also incorporates 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.

It 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 AD5338R uses 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.
