LOW VOLTAGE COMPANDER
The SL5020 contains two variable gain circuits configured for compressing and expanding
the dynamic range of an audio signal. One circuit is configured as an expander, while the
other circuit can be configured as a compressor or expander. 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 and currents required. It contains also compressor and expander mute circuit.
• Low voltage operation Vopr = 1.8 ~ 5.0V
• Decreasing external components
