ADC121S021 Datasheet (National Semiconductor)

ADC121S021, 12-Bit A/D Converter

The ADC121S021 is a low-power, single channel CMOS 12-bit analog-to-digital converter with a high-speed serial interface.

Unlike the conventional practice of specifying performance at a single sample rate only, the ADC121S021 is fully specified over a sample rate range of 50 kSPS to 200 kSPS.
