SL5020

Semiconductor SL5020/P LOW VOLTAGE COMPANDER Description 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. Features Low voltage operation Vopr = 1.8 ~ 5.0V Decreasing external components Built in compressor and expander mute circuit Unity gain level set a 100mVrms Response time adjustable Ordering Information Type NO.
