Introduction

TM2312 is a four-pair input, four-channel output digitally controlled audio processing IC, manufactured using deep sub-micron CMOS process technology. The chip integrates volume, bass, treble, channel equalization, front/rear attenuation, and loudness processing. It combines multiple selectable gain inputs in a single chip, requires minimal peripheral components, and offers excellent performance and reliability. All functions are driven and implemented via I²C bus programming. The SOP32 package features a well-organized pin layout and straightforward application circuit, making it highly conducive to PCB layout optimization and cost reduction.
