GENERAL DESCRIPTION
The AD5624R/AD5644R/AD5664R, members of the
nano
DAC
family, are low power, quad, 12-/14-/16-bit buffered voltage-out
DACs. All devices operate from a single 2.7 V to 5.5 V supply
and are guaranteed monotonic by design.
The AD5624R/AD5644R/AD5664R have an on-chip reference.
The AD56x4R-3 has a 1.25 V, 5 ppm/°C reference, giving a full-
scale output range of 2.5 V; the AD56x4R-5 has 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 and all devices can be operated from a single
2.7 V to 5.5 V supply. The internal reference is enabled via a
software write.
The part incorporates 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 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 part in normal operation makes it ideally suited to portable
battery-operated equipment.
The AD5624R/AD5644R/AD5664R use a versatile 3-wire serial
interface that operates at clock rates up to 50 MHz, and is
compatible with standard SPI, QSPI, MICROWIRE, and
DSP interface standards. The on-chip precision output amplifier
enables rail-to-rail output swing.
