4-Channel Audio Processor
PT2313H
DESCRIPTION
PT2313H is a four-channel digital control audio processor utilizing CMOS technology. Volume, Bass,
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. PT2313H is housed in 28-pin SOP package. The 28-pin version
provides additional Two Band Tone Control and Loudness Function and is pin-to-pin compatible with
TDA7313. Pin assignments and application circuits are optimized for easy PCB layout and cost saving
advantages.
