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.
