... TDA7513T 3.4.3 AutoZero In order to reduce the number of pins there coupling between the In-Gain and the following stage, so that in theory any offset generated by or before the In-Gain stage would be transferred or even amplified to the output. To avoid this undesired situation a special offset cancellation stage called AutoZero is implemented. This stage is located before the Volume block to eliminate all offsets generated by the Stereodecoder, the Input Stage and the In-Gain stage (please note that externally generated offsets, e ...
