FUNCTIONAL DESCRIPTION
Introduction
The MC33110 compander (COMpressor and exPANDER)
is composed of two variable gain circuits which provide
compression and expansion of the signal dynamic range.
The compressor will take a signal with an 80 dB dynamic
range (100
μ
V to 1.0 Vrms), and reduce that to a 40 dB
dynamic range by attenuating strong signals, while
amplifying low level signals. The expander does the opposite
in that the 40 dB signal range is increased to a dynamic
range of 80 dB by amplifying strong signals and attenuating
low level signals. The 0 dB level is internally set at 100
mVrms — that is the signal level which is neither amplified
nor attenuated. Both circuits contain the necessary precision
full wave rectifier, variable gain cell, and temperature
compensated references required for accurate and stable
performance.
Note: All dB values mentioned in this data sheet, unless
otherwise noted, are referred to 100 mVrms.
