GENERAL DESCRIPTION
The AD5629R/AD5669R devices are low power, octal, 12-/16-
bit, buffered voltage-output DACs. All devices are guaranteed
monotonic by design.
The AD5629R/AD5669R have an on-chip reference with an
internal gain of 2. The AD5629R-1/AD5669R-1 have a 1.25 V,
5 ppm/°C reference, giving a full-scale output range of 2.5 V.
have a 2.5 V 5 ppm/°C reference, giving a full-scale output range
of 5 V depending on the option selected. Devices with 1.25 V
reference selected operate from a single 2.7 V to 5.5 V supply.
Devices with 2.5 V reference selected operate from 4.5 V to 5.5 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 parts incorporate a power-on reset circuit to ensure that
the DAC output powers up to 0 V (AD5629R-1/AD5629R-2,
and remains powered up at this level until a valid write takes place.
The part contains a power-down feature that reduces the current
consumption of the device to 400 nA at 5 V and provides software-
selectable output loads while in power-down mode for any or
all DAC channels.
PRODUCT HIGHLIGHTS
1.
Octal, 12-/16-bit DACs.
2.
On-chip 1.25 V/2.5 V, 5 ppm/°C reference.
3.
Available in 16-lead LFCSP and TSSOP, and 16-ball
WLCSP.
4.
Power-on reset to 0 V or midscale.
5.
Power-down capability. When powered down, the DAC
typically consumes 200 nA at 3 V and 400 nA at 5 V.
