Overview
The ADCS7478AIMFE 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 ADCS7478 is designed as a drop-in replacement for Analog Devices AD747x 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.
