TA31101 pinout datasheet


A compander IC (Integrated Circuit) is a specialized electronic component used to implement companding, a technique used in audio processing to improve the dynamic range of analog audio signals.

Companding is a combination of compression and expansion. It involves compressing the dynamic range of an audio signal before transmission or recording, and then expanding it back to its original range during playback. The purpose of companding is to reduce the noise and improve the signal-to-noise ratio, particularly for lower-level audio signals.

1. For noise reduction, compressor and expander are incorporated into a package.

Compander ICs are commonly used in various audio applications, including telecommunications systems, broadcasting equipment, wireless communication devices, audio recording equipment, and other audio processing applications. They help reduce noise, increase the signal-to-noise ratio, and improve the overall audio quality by effectively managing the dynamic range of the audio signals.
