GENERAL DESCRIPTION

The

AD5623R/AD5643R/AD5663R,

members of the

nanoDAC®

family, are low power, dual 12-, 14-, and 16-bit buffered voltage-

out digital-to-analog converters (DAC) that operate from a single

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

The

AD5623R/AD5643R/AD5663R

have an on-chip reference.

The

AD5623R-3/AD5643R-3/AD5663R-3

have a 1.25 V,

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

AD5623R-5/AD5643R-5/AD5663R-5

have a 2.5 V, 5 ppm/°C

reference, giving a full-scale output of 5 V. The on-chip

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

reference; and all devices can be operated from a single 2.7 V to

5.5 V supply. The internal reference is turned on by writing to

the DAC.

The parts 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 part contains a 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.

Technical Support

The low power consumption of this part in normal operation

makes it ideally suited to portable, battery-operated equipment.

The

AD5623R/AD5643R/AD5663R

use a versatile, 3-wire serial

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

compatible with standard SPI®, QSPI™, MICROWIRE™, and

DSP interface standards. The on-chip precision output amplifier

enables rail-to-rail output swing to be achieved.

PRODUCT HIGHLIGHTS

1. Dual 12-, 14-, and 16-bit DAC.

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

3. Available in 10-lead MSOP and 10-lead, 3 mm ×

3 mm LFCSP.

4. Low power; typically consumes 0.6 mW at 3 V and

1.25 mW at 5 V.

5. 4.5 μs maximum settling time for the

AD5623R.
