UTC 8507 LINEAR INTEGRATED CIRCUIT COMPANDER DESCRIPTION The UTC 8507 is a automatic gain control system that is used for dynamic range compression and expansion. By companding the signal, this can reduce the noise components. The UTC 8507 includes compressor, expander, pre-amp, filter amp, limiter and mute/bypath logic. SOP-20 FEATURES * Wide Supply Voltage (2.4 ~ 7V ) * Easy Gain Control * Mute/Bypath Logic * Data In/Out Pin DIP-20 PIN CONFIGURATION FO 1 FI 2 CO 3 DI 4 19 EO 18 ERC 17 DO AGIC 5 16 EPI- CRC 6 15 EPI+ CPI- 7 14 EB CPI+ 8 13 EMUTE CB 9 GND 10 UTC 20 Vcc 12 BYPATH 11 CMUTE UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R123-006,B UTC 8507 LINEAR INTEGRATED CIRCUIT PIN DESCRIPTION PIN No. SYMBOL DESCRIPTON PIN No. SYMBOL 1 2 3 4 5 6 7 8 9 10 FO FI CO DI AGIC CRC CPICPI+ CB GND Filter Amp Output Filter Amp Input Compressor Output Data Input AC Gain Infinity Capacitor Compressor Rectifier Capacitor Compressor Inverting Input Compressor Non-Inverting Input Compressor Reference Bias Ground 11 12 13 14 15 16 17 18 19 20 CMUTE BYPATH EMUTE EB EPI+ EPIDO ERC EO Vcc DESCRIPTION Compressor Mute No companding Expander Mute Expander Reference Bias Expander Non-Inverting Input Expander Inverting Input Data Output Expander Rectifier Capacitor Expander Output Supply Voltage BLOCK DIAGRAM CRC 6 AGIC 5 DI 4 Rectifier Bypath CO 3 FI 2 Filter Amp Compressor Output Buffer + 1 Fo Variable Resistor Compressor Mute 5.1K CPI- 7 3.3k + CPI+ 8 11 CMUTE Summing Amp Limiter Logic 12 BYPATH CB Bypath EPI- 16 - EPI+ 15 + 13 EMUTE Variable Resistor Summing Amp Rectifier Expandor Mute Bias Circuit 17 18 19 9 14 10 DO ERC EO CB EB GND 20 Vcc ABSOLUTE MAXIMUM RATINGS PARAMETER Supply Voltage Power Dissipation DIP-20 SOP-20 Operating Temperature Storage Temperature UTC SYMBOL RATINGS UNIT Vcc 10 V PD Topr Tstg 1000 410 -20 ~ +70 -55 ~ +150 mW °C °C UNISONIC TECHNOLOGIES CO., LTD. 2 QW-R123-006,B UTC 8507 LINEAR INTEGRATED CIRCUIT ELECTRICAL CHARACTERISTICS (Vcc=3V,f=1kHz,Ta=25℃,unless otherwise noted) PARAMETER SYMBOL DC ELECTRICAL CHARACTERISTICS Operating Voltage Vcc Operating Current Icc COMPRESSOR PART Standard Input Voltage (0dB) VI (COMP) Gain Difference △Gv1 (COMP) △Gv2 (COMP) Bypath Gain Difference △GVB (COMP) Output Distortion THD COMP Noise Output Voltage VNO (COMP) Mute Attenuation Ratio ATT MUTE Limiting Voltage VLIM (COMP) EXPANDER PART Standard Output Level (0dB) Vo (EXP) △Gv1 (EXP) Gain Difference △Gv2 (EXP) △Gv3 (EXP) Bypath Gain Difference △GvB (EXP) Output Distortion THD EXP Noise Output Voltage VNO (EXP) Mute Attenuation Ratio ATT MUTE Limiting Voltage VOEXP (MAX) UTC TEST CONDITIONS MIN No signal Vout=300mVrms=0dB Vin=-20dB Vin=-40dB Vin=0dB,BYPATH=GND Vin=0dB Rg=620Ω Vin=0dB,CMUTE=GND Vin=30mVrms=0dB Vin=-10dB-0.5 Vin=-20dB Vin=-30dB Vin=0dB,BYPATH=GND Vin=0dB Rg=620Ω Vin=0dB,EMUTE=GND THD=10% 8.0 -0.5 -1.0 -1.5 60 1.15 110 -0.5 -1.0 -1.5 -2.5 60 700 TYP MAX UNIT 2.4 4.0 7.0 6.5 V mA 12.5 0 0 0 0.5 3.0 80 1.35 17.0 +0.5 +1.0 +1.5 1.0 5.5 mVrms 130 0 0 0 0 0.5 10.0 80 800 160 +0.5 +1.0 +2.0 +0.5 1.5 30.0 1.50 UNISONIC TECHNOLOGIES CO., LTD. dB dB % mVrms dB Vp-p mVrms dB dB % μVrms dB mVrms 3 QW-R123-006,B UTC 8507 LINEAR INTEGRATED CIRCUIT TEST CIRCUIT COMP OUT 1μF 1 + 10k FO Vcc 20 + 10μF 100k 2 FI EO 19 EXP OUT + 10K 1.0μF 1μF + 3 CO 4 DI 5 AGIC ERC 18 DO 17 EPI- 16 + + 2.2μF 50pF 51K 22μF 10K 2.2μF + 1.0μF 474 6 + CRC EPI+ 15 100k 9.1k + 0.47μF Vcc 7 CPI- EB 14 + 620 EXP IN 4.7μF 474 8 COMP IN CPI+ EMUTE 13 BYPATH 12 SW3 620 + 9 CB SW2 4.7μF 10 GND CMUTE 11 SW1 UTC UNISONIC TECHNOLOGIES CO., LTD. 4 QW-R123-006,B Vcc + 47μF 1 20 104 5.6K - 101 Filter Amp 132 19 2 18 3 + 39K 17 2.2μF - 4 Data output 10K 22μF 0.47μF + 16 Comp 5 + - 2.2μF 14 7 + + 10μF 13 223 12 9 2.2K REG LOGIC Expander Mute 1μF 103 8 8.2K 3.3K REG Expander input 47K 104 + 51K 15 6 + 473 - 33K 473 33K + 390K 473 Exp 120K + Speaker 33K TO TX Modulation + 11 10 MIC Compressor Mute 5 UNISONIC TECHNOLOGIES CO., LTD.
