Description
2.7 V to 5.5 V, dual 16-bit nanoDAC, with external
reference
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 s maximum settling time for the AD5623R.
