Overview
4-Channel Input Audio Processor 7314 DESCRIPTION 7314 is a four-channel input digital audio processor utilizing CMOS Technology.
Volume, Bass, Treble and Balance are incorporated into a single chip.
Loudness Function and Selectable Input Gain are also provided to build a highly effective electronic audio processor having the highest performance and reliability with the least external components.
All functions are programmable using the I2C Bus.
The pin assignments and application circuit are optimized for easy PCB layout and cost saving advantage for audio application.
FEATURES • • • • • • • • • • • • • CMOS technology Least external components Treble and bass control Loudness function 4 stereo inputs with selectable input gain Input/output for external noise reduction system/equalizer 2 independent speaker controls for balance control Independent mute function Volume control in 1.
25 dB/step Low distortion Low noise and DC stepping Controlled by I2C bus micro-processor interface Available in 28 Pins, DIP or SOP APPLICATIONS • • Car stereo (Audio) Hi-Fi audio system 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 7314 V1.
