TBA 440 resembles a sensitive IF amplifier, a double balanced detector and an AGC system for IF and RF with adjustable threshold and tuner delay in a comon 16 lead DIP-case. The IF-amplifier is dc-coupled from input to the video outputs and gain controlled in two stages by variable emitter-degeneration. Thus the number of external components could be minimized. The circuit offers excellent large signal capability and low noise level over the whole AGC-range. The dc-level of the video outputs and of the AGC threshold are temperature compensated.
