Overview
The Texas Instruments ADC122S051CIMMX/NOPB is a low-power, two-channel CMOS 12-bit analog-to-digital converter (ADC) designed for high-speed applications. This device operates on a single power supply ranging from 2.7V to 5.25V and is fully specified over a sample rate range of 200 ksps to 500 ksps. The ADC uses a successive-approximation register architecture with an internal track-and-hold circuit, enabling it to accept one or two input signals at inputs IN1 and IN2. The output serial data is in straight binary format and is compatible with several serial interface standards, including SPI™, QSPI™, MICROWIRE, and common DSP serial interfaces.
