Volume, Bass, Treble and Balance, Front/Rear Fader Processor are incorporated into a single chip. Loudness Function and Selectable Input Gain are also provided to build a highly effective electronic audio processor having the highest performance and reliability with the least external components. All functions are programmable using the I2C Bus. The pin assignments and application circuit are optimized for easy PCB layout and cost saving advantage for audio application. Housed in a 28-pin DIP/SO Package, PT2313L is pin-to-pin compatible with TDA7313 and is very similar in performance with the later. Features ! ! ! ! ! ! ! ! ! ! ! ! !
