GENERAL DESCRIPTION

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

standards.

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 V

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.
