GENERAL DESCRIPTION
The AD5662, a member of the nanoDAC family, is a low power,
single, 16-bit buffered voltage-out DAC that operates from a
single 2.7 V to 5.5 V supply and is 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 to 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
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 power consumption is 0.75 mW at 5 V, going down to
2.4 μW in power-down mode.
The AD5662’s on-chip precision output amplifier allows rail-to-
rail output swing to be achieved. For remote sensing applications,
the output amplifier’s inverting input is available to the user.
The AD5662 uses 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.
