Overview
The ADC124S051CIMM/NOPB from Texas Instruments is a low-power, four-channel CMOS 12-bit analog-to-digital converter (ADC) designed for high-speed applications. This converter is distinguished by its operation over a range of sample rates from 200 ksps to 500 ksps, unlike many ADCs that are specified at a single sample rate. It employs a successive-approximation register architecture with an internal track-and-hold circuit, allowing it to accept up to four input signals. The device operates with a single power supply ranging from 2.7V to 5.25V and is packaged in a 10-lead VSSOP package, ensuring operation over the industrial temperature range of −40°C to +85°C.
