Introduction

TM2314 is a four-pair input, two-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 delivers excellent performance and reliability. All functions are driven and implemented through I²C bus programming. The TM2314 adopts an SOP28 package. With a well-organized pin layout and simple application circuit, it is highly conducive to PCB layout optimization and cost reduction.
