Overview
The Texas Instruments ADCS7476AIMFX/NOPB is a low-power, monolithic CMOS analog-to-digital converter (ADC) designed for high-speed data acquisition. This device operates at a conversion rate of 1 million samples per second (MSPS) and is available in 12-bit, 10-bit, and 8-bit resolutions. It is packaged in a 6-pin SOT-23 package, making it suitable for space-constrained applications. The ADCS7476AIMFX/NOPB is based on a successive approximation register architecture with an internal track-and-hold circuit, and it uses the supply voltage as a reference, allowing for a full-scale input range of 0 to VDD.
