GENERAL DESCRIPTION

10B

The

AD5629R/AD5669R

devices are low power, octal, 12-/16-

bit, buffered voltage-output DACs. All devices are guaranteed

monotonic by design.

The

AD5629R/AD5669R

have an on-chip reference with an

internal gain of 2. The

AD5629R-1/AD5669R-1

have a 1.25 V,

5 ppm/°C reference, giving a full-scale output range of 2.5 V.

The

AD5629R-2/AD5629R-3

and the

AD5669R-2/AD5669R-3

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

of 5 V depending on the option selected. Devices with 1.25 V

reference selected operate from a single 2.7 V to 5.5 V supply.

Devices with 2.5 V reference selected operate from 4.5 V to 5.5 V.

The on-chip reference is off at power-up, allowing the use of an

external reference. The internal reference is enabled via a

software write.

The parts incorporate a power-on reset circuit to ensure that

the DAC output powers up to 0 V (AD5629R-1/AD5629R-2,

AD5669R-1/AD5669R-2)

or midscale (AD5629R-3/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.

PRODUCT HIGHLIGHTS

Octal, 12-/16-bit DACs.

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

Available in 16-lead LFCSP and TSSOP, and 16-ball

WLCSP.

Power-on reset to 0 V or midscale.

Power-down capability. When powered down, the DAC

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