4-Channel Audio Processor IC
Description
PT2313L
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 I
2
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.
