Overview
The ADCS7476AIMF/NOPB is a low-power, monolithic CMOS 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device operates at a conversion rate of 1 MSPS and is designed as a drop-in replacement for Analog Devices AD7476. It features a successive approximation register (SAR) architecture with an internal track-and-hold circuit. The ADCS7476 is packaged in a compact 6-pin SOT-23 package, making it ideal for applications where space is a critical consideration. It operates over an extended temperature range of -40°C to 125°C, suitable for both automotive and industrial environments.
