DESCRIPTION
The DAC121S101 is a full-featured, general purpose
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 just 177 µA of current at 3.6 V.
The on-chip output amplifier allows rail-to-rail output
swing and the three wire serial interface operates at
clock rates up to 20 MHz over the specified supply
voltage range and is compatible with standard SPI,
QSPI, MICROWIRE and DSP interfaces.
The supply voltage for the DAC121S101 serves as its
voltage reference, providing the widest possible
output dynamic range. 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.
The low power consumption and small packages of
the DAC121S101 make it an excellent choice for use
in battery operated equipment.
The DAC121S101 operates over the extended
temperature range of -55°C to +125°C.
