GENERAL DESCRIPTION

The

AD5627R/AD5647R/AD5667R, AD5627/AD5667

members

of the

nanoDAC

family are low power, dual, 12-, 14-, 16-bit

buffered voltage-out digital-to-analog converters (DACs)

with/without on-chip reference. All devices operate from a single

2.7 V to 5.5 V supply, are guaranteed monotonic by design, and

have an I

C-compatible serial interface.

The

AD5627R/AD5647R/AD5667R

have an on-chip reference.

The

AD5627RBCPZ, AD5647RBCPZ,

and

AD5667RBCPZ

have a

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

the

AD5627RBRMZ

and

AD5667RBRMZ

have a 2.5 V, 5 ppm/°C

reference, giving a full-scale output range of 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

AD5667

and

AD5627

require an external reference voltage

to set the output range of the DAC.

The

AD5627R/AD5647R/AD5667R, AD5627/AD5667

incorporate a power-on reset circuit that ensures the DAC

output powers up to 0 V, and remains there until a valid write

takes place.

The device contains a per-channel power-down feature that

reduces the current consumption of the device to 480 nA at 5 V

and provides software-selectable output loads while in power-

down mode. The low power consumption of this device in

normal operation makes it ideally suited to portable battery-

operated equipment. The on-chip precision output amplifier

enables rail-to-rail output swing.

The

AD5627R/AD5647R/AD5667R, AD5627/AD5667

use a

2-wire I

C-compatible serial interface that operates in standard

(100 kHz), fast (400 kHz), and high speed (3.4 MHz) modes.
