ECG904

ECG904: Quad general-Purpose Operational Amplifier packaging four independent, high-gain, internally frequency-compensated operational amplifiers onto a single 14-pin substrate frame. It functions natively off single or split power rails to handle analog signal tracking, active filtering, and linear summation, widely deployed across automotive control modules and industrial monitoring loops.
