2.4V~7V

COMP output deviation (Typ)

-0.5dB~0.5dB

EXP output deviation (Typ)

-1.5dB~1.5dB

COMP output noise(Typ)

3mV

EXP output noise(Typ)

10μV

Packaging form

SOP20/DIP20
Overview:

D5015 is a noise reduction circuit for cordless telephones. A compression expander circuit comprising a compressor and an expander. The compression expander reduces transmission noise and extends the received signal by compressing and transmitting the input signal. The circuit has the characteristics of only a few peripheral components and low voltage operation.
