3 Description
The DAC082S085 device is a full-featured, general-
purpose, 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.
