Audio Processor IC
PT2313L is a four-channel digital control audio processor utilizing CMOS Technology. 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 I2 C 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.
