TDA4340X Overview
Power Supply, Reference Current A temperature stable, low noise reference voltage generator is used for better ripple rejection and for the generation of a reference current. This current is used as a time base for the deemphasis, the gate time of the pulse former, and the pilot cancellation, avoiding temperature and tolerance effects. MPX Input, MPX Filter Adjusting the value of the input resistor, the MPX input...
