TDA5360
The aim of the TAC is to limit the amplitude and the duration of the perturbation seen at the reader output.
Because thermal asperity amplitude is not constant, the TAC need some threshold programmation to define
the sharpness of the response.
note that reducing the TAC threshold also impact the Low corner frequency value of the read amplifier.
