U7313

UNISONIC TECHNOLOGIES CO., LTD U7313 AUDIO PROCESSOR IC „ DESCRIPTION The U7313 is a 3-stereo inputs and 4-speaker outputs digital audio processor which incorporates volume, tone(bass and treble) , balance(left/right)and fader(front/rear) into a single chip. Selectable input gain and loudness function are provided to build a highly effective electronic audio processor having the highest performance and reliability with the external components. The AC signal setting is obtained by resistor networks and switches which are set by programming serial input signal via I2C bus. In addition, BiCOMS processes are utilized for low distortion, low noise and low DC stepping. The U7313 is designed for quality audio applications in car radio and Hi-Fi systems. „ FEATURES * Support I2C bus interface * 3 stereo inputs and selectable input gain * Volume control in 1.25dB/step * Loudness function * Bass and treble control * 4 independent speakers control * Independent mute function * Low distortion * Low noise and DC stepping „ ORDERING INFORMATION Ordering Number Lead Free Halogen Free U7313L-D28-T U7313G-D28-T U7313L-S28-R U7313G-S28-R U7313L-S28-T U7313G-S28-T Package DIP-28 SOP-28 SOP-28 Packing Tube Tape Reel Tube CMOS IC www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd 1 of 14 QW-R502-173.B U7313 „ PIN CONFIGURATION CREF VDD GND L R INR OUTR LOUDR R3 R2 R1 LOUDL L3 L2 1 2 3 4 5 6 7 8 9 10 11 12 13 14 28 SCL 27 SDA 26 DIGGND 25 OUTLF 24 OUTRF 23 ...
