Overview
The ADCS7476AIMFX is a low-power, monolithic CMOS analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADCS747x series, which includes 12-, 10-, and 8-bit ADCs operating at a conversion rate of 1 MSPS. The ADCS7476 is designed as a drop-in replacement for Analog Devices AD747x and is based on a successive approximation register architecture with an internal track-and-hold circuit. It is compatible with various serial interfaces such as SPI, QSPI, MICROWIRE, and many common DSP serial interfaces.
