Overview
The ADC124S051 is a low-power, four-channel CMOS 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. It features a high-speed serial interface and is designed to operate over a sample rate range of 200 ksps to 500 ksps. The converter uses a successive-approximation register architecture with an internal track-and-hold circuit, allowing it to accept up to four input signals. The ADC124S051 is packaged in a 10-lead VSSOP package and operates within an industrial temperature range of −40°C to +85°C.
