PT2313L

PT2313L 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. PT2313L is housed in 20-pin or 28-pin DIP/SOP Package. The 28pin 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 · Input/Output for External Noise Reduction System/Equalizer · 4 Independent Speaker Controls for Fader and Balance · Independent Mute Function · Volume Control in 1.25 dB/step · Low Distortion · Low Noise and DC Stepping · Controlled by I2C Bus Micro-Processor Interface · Pin-to-Pin Compatible with TDA7313 (for 28-pin version)

Applications
· Car Stereo (Audio) · Hi-Fi Audio System · LCD Monitor

Note: Purchase of I2C Component of Princeton Technology Corporation (PTC) conveys a license under Philips I2C Patent Right to use these components in any I2C System, provided that the system conforms to the I2C Standard Specification defined by Philips
