PT2313L SMD IC AUDIO PROCESSOR IC SOP-28 PT2313L

Product Overview:

A surface-mount, four-channel input digital audio processor integrated circuit designed for quality audio applications in car stereos and high-fidelity audio systems. It utilizes CMOS technology to integrate volume, bass, treble, and balance controls alongside a selectable input gain stage, allowing full software configuration over a serial interface.

Core Specifications:

Manufacturer: Princeton Technology Corp. (PTC)

Package Type: SOP-28

Function: Four-Channel Digital Audio Processor

Input Channels: 4 Stereo Inputs (comprising three stereo single-ended inputs and one specialized stereo input)

Control Interface: I2C Bus Interface

Features

• Integrated Audio Controls: Built-in electronic volume, bass, treble, and balance adjustments to minimize external discrete component needs.

• Selectable Input Gain: Features software-programmable input gain stages to perfectly match different audio source levels.

• Loudness Function: Includes an internal loudness function to boost audio dynamics at lower listening levels.

• Four Independent Speaker Outputs: Provides four separate speaker output channels with independent volume attenuators for advanced fade and balance capabilities.

• Low Distortion and Noise: Engineered with high-performance audio routing pathways to maintain low total harmonic distortion and low signal noise.

• Standardized Digital Control: Utilizes a standard two-wire serial bus interface for direct control by a master system microcontroller.

Applications

• Car Stereo Systems: Manages multi-channel fading, source selection, and equalization in automotive head units.

• Hi-Fi Audio Electronics: Acts as the central pre-amplifier and tone controller in high-fidelity home theater receivers.

• Multimedia Entertainment Centers: Coordinates audio source switching and equalization processing in compact speaker docks and soundbars.
