TM(Shenzhen Titan Micro Elec) TM2313

TM2313 is a three-input, four-channel output digitally controlled audio processing IC. Manufactured using deep sub-micron CMOS process technology, it integrates volume, bass, treble, channel equalization, front/rear attenuation, and loudness processing on a single chip. Multiple selectable gain inputs are consolidated in one chip, minimizing external components while delivering excellent performance and reliability. All functions are driven and implemented via I²C bus programming. The TM2313 is available in SOP28/DIP28 packages. The rational pin layout and simple application circuit are highly conducive to PCB layout optimization and cost reduction.
