SL5015/P
COMPANDOR
Description
The SL5015/P is an noise reduction IC for cordless phone. It is a compandor IC that consist
of a compressor and an expander. Compandor reduces transmission noise by compressing
and transmitting out going signals and expanding received signals.
The ICs are designed for minimum requirement of external components and for low voltage
operation. Small size is an advantage when used in equipment in which space is a premium.
For DATA, input and output terminals are provided for convenience. Two styles of packaging,
DIP and SOP, are available to meet different requirements.
