The AD5308/AD5318/AD5328 are octal 8-, 10-, and 12-bit
buffered voltage output DACs in a 16-lead TSSOP. They operate
from a single 2.5 V to 5.5 V supply, consuming 0.7 mA typical
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 AD5308/
AD5318/AD5328 use 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
The references for the eight DACs are derived from two
reference pins (one per DAC quad). These reference inputs can
be configured as buffered, unbuffered, or VDD inputs. 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 to the device takes place. The outputs of all DACs may be
updated simultaneously using the asynchronous LDAC input.
The parts contain a power-down feature that reduces the current
consumption of the devices to 400 nA at 5 V (120 nA at 3 V).
The eight channels of the DAC may be powered down individually.
All three parts are offered in the same pinout, which allows
users to select the resolution appropriate for their application
without redesigning their circuit board.
