Octal, 12-/16-Bit DAC, I²C^®, 5ppm/°C On-

Chip Reference in 4mm X 4mm LFCSP

AD5629R/AD5669R

Preliminary Technical Data

(AD5669R-3) and remains powered up at this level until a valid

write takes place. The part contains a power-down feature that

reduces the current consumption of the device to 400 nA at 5 V

and provides software-selectable output loads while in power-

down mode for any or all DAC channels.

FEATURES

Low power, smallest-pin-compatible octal DACs

AD5669R: 16 bits

AD5629R: 12 bits

4mm X 4mm 16-lead LFCSP and 16-lead TSSOP

User selectable on-chip 1.25 V/2.5 V, 5 ppm/°C reference

Power down to 400 nA @ 5 V, 200 nA @ 3 V

2.7 V to 5.5 V power supply

Guaranteed monotonic by design

Power-on reset to zero scale or midscale

3 power-down functions

GENERAL DESCRIPTION

The AD5629R/AD5669R devices are low power, octal, 12-/16-

bit, buffered voltage-output DACs. All devices operate from a

single 2.7 V to 5.5 V supply and are guaranteed monotonic by

design.

The AD5629R/AD5669R has an on-chip reference with an

internal gain of 2. The AD5629R/AD5669R has a user selectable

1.25 V 5 ppm/°C reference, giving a full-scale output range of

2.5 V or a 2.5 V 5 ppm/°C reference, giving a full-scale output

range of 5 V depending on the option selected. The on-chip

reference is off at power-up, allowing the use of an external refer-

ence. The internal reference is enabled via a software write. The

AD5669/AD5629 require an external reference voltage to set

the output range of the DAC.

PRODUCT HIGHLIGHTS

1. Octal, 12-/16-bit DAC.

2. On-chip 1.25 V/2.5 V, 5 ppm/°C reference.

3. Available in 16-lead LFCSP/16-lead TSSOP.

4. Power-on reset to 0 V or midscale.

5. Power-down capability. When powered down, the DAC

typically consumes 200 nA at 3 V and 400 nA at 5 V.

The part incorporates a power-on reset circuit that ensures that the

DAC output powers up to 0 V (AD5629R/AD5669R) or midscale
