Overview
The ADCS7476AIMFE/NOPB 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-bit, 10-bit, 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 series and features a successive approximation register architecture with an internal track-and-hold circuit. It is packaged in a compact 6-pin SOT-23 package, making it ideal for applications where space is critical.
The device operates on a single supply voltage ranging from 2.7 V to 5.25 V and uses the supply voltage as a reference, allowing for a full-scale input range of 0 to VDD. The serial interface is compatible with SPI, QSPI, MICROWIRE, and many common DSP serial interfaces.
