Description
2.7 V to 5.5 V, dual 16-bit
nanoDAC,
with external
reference
APPLICATIONS
Process control
Data acquisition systems
Portable battery-powered instruments
Digital gain and offset adjustment
Programmable voltage and current sources
Programmable attenuators
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.

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.
