DAC121S101 Datasheet PDF - TI

●Description

●The DAC121S101 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 30 MHz over the specified supply voltage range and is compatible with standard SPI™, QSPI, MICROWIRE and DSP interfaces. Competitive devices are limited to 20-MHz

●clock rates at supply voltages in the 2.7 V to 3.6 V range.
