Overview:

D5020 is a gain adjustable compression and expansion circuit. It consists of two channels, one for expansion and the other for compression or expansion. The circuit contains small signal full wave rectification, detection signal size, used to adjust the input or feedback channel gain size. With better temperature characteristics of band gap precision reference source, noise function. Circuit operating voltage low, peripheral components less.

Main features:

● Working low voltage Vopr= 1.8 -~5.0V
● Few peripheral components
● Including compressor and expander noise circuit
● Unit-gain level set to 100mVrms
● Response time adjustable
● Package form: DIP14, SOP14

Application:

● 1.5V Stereo Headphones
