12-Bit Micro Power Digital-to-Analog Converter with Rail-to-Rail Output - DAC121S101QML-SP

DAC121S101QML-SP (ACTIVE)

12-Bit Micro Power Digital-to-Analog Converter with Rail-to-Rail Output

 

Description

The DAC121S101QML-SP device 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 DAC121S101QML-SP 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 DAC121S101QML-SP make it an excellent choice for use in battery-operated equipment.
