Overview
The ADCS7478AIMFE/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 resolution options. It operates at a sampling rate of 1 MSPS and is designed for applications requiring fast and precise data conversion. The ADCS7478AIMFE/NOPB is packaged in a compact 6-pin SOT-23 package, making it suitable for space-constrained applications. It supports a wide operating voltage range from 2.7V to 5.25V and features a successive approximation register (SAR) architecture with an internal track-and-hold circuit.
