描述 Description

Advance Information
Low Voltage CompanderThe MC33111 contains two variable gain circuits configured for compressing and expanding the dynamic range of an audio signal. One circuit is configured as an expander, and the other is configured as a compressor. Each circuit has a full wave rectifier to provide average value
information to a variable gain cell located in either the input stage or the feedback path. An internal temperature stable bandgap reference provides the necessary precision voltages.•Operating Supply Voltage: 3.0 V to 7.0 V
•Output Voltage Swing = 2.8 Vp-pwith VCC= 3.0 V
•No Precision External Components Required
•60 dB Dynamic Range Compressed to 30 dB, Re-expandable to 60 dB
•Unity Gain Level set at 100 mVrms
•Attack and Decay Times Adjustable
•Mute and Passthrough Controls
•Two Uncommitted Op Amps
•Temperature Compensated Reference
•Available in Standard DIP and Surface Mount Packages
