GENERAL DESCRIPTION
The AD5302/AD5312/AD5322 are dual 8-, 10-, and 12-bit
buffered voltage output DACs in a 10-lead MSOP that operate
from a single 2.5 V to 5.5 V supply, consuming 230 μA at 3 V.
Their on-chip output amplifiers allow the outputs to swing rail-
to-rail with a slew rate of 0.7 V/μs. The AD5302/AD5312/AD5322
utilize 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 references for the two DACs are derived from two reference
pins (one per DAC). The reference inputs can be configured as
buffered or unbuffered inputs. The outputs of both DACs can be
updated simultaneously using the asynchronous LDAC input.
The parts incorporate a power-on reset circuit, which ensures
that the DAC outputs power-up to 0 V and remain there until a
valid write takes place to the device. The parts contain a power-
down feature that reduces the current consumption of the
devices to 200 nA at 5 V (50 nA at 3 V) and provides software-
selectable output loads while in power-down mode.
The low power consumption of these parts in normal operation
makes them ideally suited for portable battery-operated
equipment. The power consumption is 1.5 mW at 5 V, 0.7 mW
at 3 V, reducing to 1 μW in power-down mode.
