April 2005 .. ADC124S021 4 Channel, 200 kSPS, 12-Bit A/D Converter ADC124S021 4 Channel, 200 kSPS, 12-Bit A/D Converter General Description The ADC124S021 is a low-power, four-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 ADC124S021 is fully specified over a sample rate range of 50 kSPS to 200 kSPS. The converter is based on a successive-approximation register architecture with an internal track-and-hold circuit. It can be configured to accept up to four input signals at inputs IN1 through IN4. The output serial data is straight binary, and...
