The ADC121S021CIMF is a 12-bit CMOS successive-approximation Analogue-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 to 200kSPS. The low-power single channel converter is based upon successive-approximation register architecture with an internal track-and-hold circuit. The output serial data is straight binary and is compatible with several standards, such as SPI?, QSPI?, MICROWIRE and many common DSP serial interfaces. The ADC operates with a single supply that can range from +2.7 to +5.25V.
