Product specification
Television IF amplifier and demodulator
TDA8340
TDA8341
AGC control circuit
This converts the AGC detector voltage (pin 14) into a current signal which controls the gain of the IF amplifier. It also
provides a tuner AGC control output from pin 4, current limiting is incorporated to prevent internal damage. The AGC
starting point is adjusted via pin 3.
AFC circuit
The AFC circuit provides a voltage output which controls the IF frequency of the tuner. Video information on the AFC
output (pin 5) is eliminated by a sample-and-hold circuit (external capacitor at pin 6). Coupling between the AFC and
reference tuned circuits is via two small capacitors (or parasitic capacitance) between the respective tracks of the printed
circuit board. If the capacitance is less than 1 pF, the steepness of the AFC characteristic is reduced.
