DAC121S101QML
July 15, 2009
12-Bit Micro Power Digital-to-Analog Converter with Rail-
to-Rail Output
General Description
The DAC121S101 is a full-featured, general purpose 12-bit
voltage-output digital-to-analog converter (DAC) that can op-
erate from a single +2.7 V to 5.5 V supply and consumes just
177 A of current at 3.6 V. The on-chip output amplifier allows
rail-to-rail output swing and the three wire serial interface op-
erates 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.
