Silan Semiconductors SA8507 COMPANDER DESCRIPTION SA8507 is a automatic gain control system that is used for dynamic range compression and expansion. According to the companding the signal, this can reduce the noise components. SA8507 includes compressor, expander, pre-amp, filter amp, limiter DIP-20 and mute/bypath logic. FEATURES * Wide supply voltage: 2.4V ~ 7V * Easy gain control SOP-20 * Mute/bypath logic * Data in/out pin ORDERING INFORMATION SA8507D DIP-20-300 Package SA8507S SOP-20-375 Package PIN CONFIGURATION 1 20 Vcc FI 2 19 EO CO 3 18 ERC DI 4 17 DO AGIC 5 CRC 6 CPI- 7 14 EB CPI+ 8 13 EMUTE CB 9 12 BYPATH SA8507 FO GND 10 16 EPI15 EPI+ 11 CMUTE HANGZHOU SILAN MICROELECTRONICS JOINT-STOCK CO.,LTD REV: 1.1 1 2001-11-30 Silan Semiconductors SA8507 BLOCK DIAGRAM AGIC CRC DI CO FI 5 6 4 3 2 Rectifier Compressor Output Buffer Byath + - 1 FO Variable Resistor Compressor Mute CPICPI+ 7 8 Summing AMP + - Limiter 11 CMUTE Byath EPI- 16 Logic + - EPI+ 15 Variable Resistor Summing AMP Rectifier Expandor Mute 17 18 19 DO ERC EO 12 BYPATH 13 EMUTE Bias Circuit 9 14 20 Vcc 10 CB EB GND ABSOLUTE MAXIMUM RATINGS(Ta=25°C ) Characteristic Supply Voltage Power Dissipation SA8507D SA8507S Symbol Value Unit VCC 10 V PD 1000 mW 410 mW Operating Temperature TOPR -22 ~ +70 °C Storage Temperature TSTG -55 ~ +150 °C ELECTRICAL CHARACTERISTICS (Ta=25°C) Characteristic Symbol Test Condition Min Typ.
