Codec
Encodes and Decodes Data
A Codec is a semiconductor IC that digitally encodes or decodes data or signals. During the coding process, the analog signals are not digitalized without loss. There is a dynamic reduction of the analog signal and a data compression of the digital signal. This allows the required storage capacity and bandwidth for transmission to be reduced.
The majority of modern Codecs are already highly integrated and offer a whole range of additional functions. For example, a digital volume control, outputs for headphones and normal or special speakers are integrated in most cases. Often several channels are combined in one module, which saves a lot of space on the PCB. Furthermore, the resolution of the ADC/DAC can be configured very differently depending on the application. In the audio sector, for example, a very high resolution is used. This is not necessary for a speech alone function.
