1 Overview

The DAC121S101-SEP is a radiation-tolerant, full featured, general purpose, 12-bit digital-to-analog converter (DAC) that can operate from a single 2.7V to 5.5V supply and consumes just 177uA current at 3.6V. The on-chip output amplifier allows rail-to-rail output swing and the three-wire serial interface operates at clock rates up to 30MHz over the specified supply voltage range. The device uses CMOS7 technology and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interfaces. The supply voltage (VA) for the DAC121S101-SEP serves as the voltage reference, providing the widest possible output dynamic range. A power-on reset circuit maintains 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 one micro Watt (typ).

See the DAC121S101-SEP product page on ti.com for more details.
