MC33111P中文资料Low Voltage Compander Silicon Monolithic Integrated Circuit数据手册Lansdale规格书

描述 Description

The ML33111 contains two variable gain circuits configured for compress ing 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. Included in the ML33111 are controls for muting each section independently, and for pass through of both. Two uncommitted op amps are available for peripheral functions.
