3 Description

The DAC088S085 is a full-featured, general-purpose,

OCTAL, 8-bit, voltage-output, digital-to-analog

converter (DAC) that can operate from a single 2.7 V

to 5.5 V supply and consumes 1.95 mW at 3 V and

4.85 mW at 5 V. The DAC088S085 is packaged in a

16-pin WQFN package and a 16-pin TSSOP

package. The WQFN package makes the

DAC088S085 the smallest OCTAL DAC in its class.

The on-chip output amplifiers allow rail-to-rail output

swing and the three-wire serial interface operates at

clock rates up to 40 MHz over the entire supply

voltage range. Competitive devices are limited to

25‑MHz clock rates at supply voltages in the range of

2.7 V to 3.6 V. The serial interface is compatible with

standard SPI™, QSPI, MICROWIRE, and DSP

interfaces. The DAC088S085 also offers daisy chain

operation where an unlimited number of devices can

be updated simultaneously using a single serial

interface.
