The DAC124S085 device is a full-featured, general-purpose, quad, 12-bit, voltage-output,
digital-to-analog 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.
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 DAC124S085 make it an excellent
choice for use in battery-operated equipment.
The DAC124S085 is one of a family of pin-compatible DACs, including the 8-bit DAC084S085
and the 10-bit DAC104S085. The DAC124S085 operates over the extended industrial temperature range
of 40°C to 105°C.
