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.
