4 Channel Audio Processor PT2312
D*CRIPTION
PT2312 is a four-channel di*al control audio processor utilizing CMOS Technology. Volume, B*,
Balance, Front/Rear Fader Processor, Selectable Input Gain are incorporated into a single chip having
the highest performance and reliability with the least external components. All functions are
programmable using the I2C Bus. PT2312 is housed in 32-pin, SOP Package. 4 stereo inputs with
selectable input gain, 2-band tone control (treble & b*), balance, fader and loudness function are
incorporated into a single chip having the highest performance and reliability. Pin *ignments and
application circuits are optimized for easy PCB layout and cost saving advantages.
