Overview
The ADCS7476AIMF from Texas Instruments is a low-power, monolithic CMOS analog-to-digital converter (ADC) available in 12-, 10-, and 8-bit resolutions. This device operates at a conversion rate of 1 MSPS and is designed as a drop-in replacement for Analog Devices AD747x series. The ADCS7476AIMF is based on a successive approximation register architecture with an internal track-and-hold circuit. It features a serial interface compatible with SPI, QSPI, MICROWIRE, and various DSP serial interfaces. The device uses the supply voltage as a reference, allowing it to operate with a full-scale input range of 0 to VDD. It is packaged in a 6-pin SOT-23 package and supports a single supply voltage ranging from 2.7 V to 5.25 V.
