The AD5662 parts are a member of the
nano
DAC
TM
family of
devices. They are low power, single, 16-bit buffered voltage-out
DACs. All devices operate from a single 2.7 V to 5.5 V, and are
guaranteed monotonic by design.
The AD5662 requires an external reference voltage to set the
output range of the DAC. The part incorporates a power-on-
reset circuit that ensures the DAC output powers up to 0 V
(AD5662x-1) or midscale (AD5662x-2), 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
200 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 power consumption is 0.7 mW at 5 V, reducing to 1 μW in
power-down mode.
The AD5662’s on-chip precision output amplifier allows rail-to-
rail output swing to be achieved. The AD5662 utilizes a versatile
3-wire serial interface that operates at clock rates up to 30 MHz,
and is compatible with standard SPI, QSPI, MICROWIRE,
and DSP interface standards.
The AD5662 is designed with new technology, and is the next
generation to the AD53xx family.
PRODUCT HIGHLIGHTS
1.
16-bit DAC; true 12-bit accuracy guaranteed.
2.
Available in 8-lead SOT-23 and 8-lead MSOP package.
3.
Power-on-reset to zero or midscale.
4.
Low power. Operates with 2.7 V to 5.5 V supply. Typically
consumes 0.35 mW at 3 V and 0.7 mW at 5 V, making it
ideal for battery-powered applications.
