Overview
The ADC124S021CIMMX/NOPB is a low-power, four-channel CMOS 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is notable for its high-speed serial interface and its ability to operate over a range of sample rates from 50 ksps to 200 ksps. The ADC is based on a successive-approximation register architecture with an internal track-and-hold circuit, allowing it to accept up to four input signals at inputs IN1 through IN4. The output serial data is straight binary and is compatible with several standards, including SPI™, QSPI™, MICROWIRE, and many common DSP serial interfaces.
