3 Description

The DAC082S085 device is a full-featured, generalpurpose,

DUAL, 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 0.6 mW at 3 V and 1.6

mW at 5 V. The DAC082S085 is packaged in 10-pin

SON and VSSOP packages. The 10-pin WSON

package makes the DAC082S085 the smallest DUAL

DAC in its class. The on-chip output amplifier allows

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 2.7 V to 3.6 V range. The serial interface is

compatible with standard SPI™, QSPI, MICROWIRE,

and DSP interfaces.
