Product specification
SA575
DESCRIPTION
The SA575 is a precision dual gain control circuit designed for low
voltage applications. The SA575’s channel 1 is an expandor, while
channel 2 can be configured either for expandor, compressor, or
automatic level controller (ALC) application.
FEATURES

• Reference voltage of 100mV_RMS = 0dB
• One dedicated summing op amp per channel and two extra
uncommitted op amps
• 600Ω drive capability
• Single or split supply operation
• Wide input/output swing capability
• 3000V ESD protection
APPLICATIONS
• Portable communications
• Cellular radio
• Cordless telephone
• Consumer audio
