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-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
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.
A power-on reset circuit ensures that the DAC output powers up to zero volts and remains
there until there is a valid write to the device. A power-down feature reduces power consumption to
less than a microWatt with three different termination options.
The low power consumption and small packages of the DAC102S085 make it an excellent
choice for use in battery-operated equipment.
The DAC102S085 is one of a family of pin compatible DACs, including the 8-bit DAC084S085
and the 12-bit DAC122S085. The DAC102S085 operates over the extended industrial temperature range
of 40°C to 105°C.
