ADC121S021 Single Channel, 200 ksps, 12-Bit A/D Converter October 2005 ADC121S021 Single Channel, 200 ksps, 12-Bit A/D Converter General Description 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. The converter is based upon a successiveapproximation register architecture with an internal trackand-hold circuit. The output serial data is straight binary, and is patible with several standards, such as SPI™, QSPI™, MICROWIRE, and many mon DSP...
