4-Channel Audio Processor

PT2311

DESCRIPTION

PT2311 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 I

C Bus. PT2311 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.

FEATURES

• CMOS Technology

• Least External Components

• Treble and Bass Control (available only in the 28-pin version)

• Loudness Function (available only in the 28-pin version)

• 3 Stereo Inputs with Selectable Input Gain
