GENERAL DESCRIPTION
The AD5660 parts are a member of the
nanoDAC
family of
devices. They are low power, single, 16-bit buffered voltage-out
DACs, guaranteed monotonic by design.
The AD5660x-1 operate from a 3 V single supply featuring an
internal reference of 1.25 V and an internal gain of 2. The
AD5660x-2/3 operate from a 5 V single supply featuring an
internal reference of 2.5 V and an internal gain of 2. Each
reference has a 10 ppm/°C max temperature coefficient. The
reference associated with each part is available at the REFOUT
pin.
The part incorporates a power-on reset circuit that ensures that
the DAC output powers up to 0 V (AD5660x-1/2) or midscale
(AD5660x-3) 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 AD5660 uses a versatile three-wire serial interface that
operates at clock rates up to 30 MHz and is compatible with
standard SPI™, QSPI™, MICROWIRE™ and DSP interface
standards. Its on-chip precision output amplifier allows rail-to-
rail output swing to be achieved.
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 AD5660 is designed with new technology and is the next
generation to the AD53xx family.
