PT2313 is a 4-channel digital control audio processor providing Volume, Bass, Treble and Balance control functions to your audio circuits and amplifiers. Loudness function and selectable input gain are also provided to build a highly effective electronic audio processor having the highest performance and reliability with least external components. All functions are programmable using I2C bus.

Housed in 28 pin SOIC package PT2313 is a pin drop replacement for TDA7313 and very similar in performance with it.

• Least external components count
• Trebel and Bass control
• Loudness function
• 3 Stereo inputs with selectable gain
• I/O for external noise reduction syste, / equalizer
• 4 independent speaker controls for fader and balance
• Independent mute function
• Volume control in 1.25 dB/step
• Low distortion
• Low noise and DC stepping
• Pin compatible to TDA7313
• Easy to control using any microcontroller like Arduino, 8051, PIC over I2C bus.

Applications includes car stereo and all kind of Hi-Fi audio systems.
