TDA8946 Application
In VX32L TV the TDA8946AJ is a dual-channel audio power amplifier with DC gain control. It has an
output power of 2
10 W at an 8
load and a 12 V supply.
Block diagram
1. Input configuration
The TDA8946AJ inputs can be driven symmetrical (floating) as well as asymmetrical. In the
asymmetrical mode one input pin is connected via a capacitor to the signal source and the other
input is connected to the signal ground. The signal ground should be as close as possible to the
SVR (electrolytic) capacitor ground. Note that the DC level of the input pins is half of the supply
voltage VCC, so coupling capacitors for both pins are necessary
