3 Description
The DAC124S085 device is a full-featured, generalpurpose,
quad, 12-bit, voltage-output, digital-toanalog
converter (DAC) that can operate from a
single 2.7-V to 5.5-V supply and consumes 1.1 mW
at 3 V and 2.4 mW at 5 V. The DAC124S085 is
packaged in 10-pin WSON and VSSOP packages.
The 10-pin SON package makes the DAC124S085
the smallest quad 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.
The reference for the DAC124S085 serves all four
channels and can vary in voltage between 1 V and
VA, providing the widest possible output dynamic
range. The DAC124S085 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. All four outputs can be updated
simultaneously or individually depending on the
setting of the two mode of operation bits.
