3 Description

The DAC102S085 is a full-featured, general-purpose

DUAL 10-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 DAC102S085 is packaged in 10-pin WSON

and VSSOP packages. The 10-pin WSON package

makes the DAC102S085 the smallest DUAL DAC in

its class. The on-chip output amplifier allows rail-torail

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.

The reference for the DAC102S085 serves both

channels and can vary in voltage between 1 V and

VA, providing the widest possible output dynamic

range. The DAC102S085 has a 16-bit input shift

register that controls the outputs to be updated, the

mode of operation, the power-down condition, and

the binary input data. Both outputs can be updated

simultaneously or individually depending on the

setting of the two mode of operation bits.
