DESCRIPTION

The TDA2540 and 2541 are IF amplifier and A.M.

demodulator circuits for colour and black and white

television receivers using PNP or NPN tuners. They

are intended for reception of negative or positive

modulation CCIR standard.

They incorporate the following functions :

.

Gain controlled amplifier

.

Synchronous demodulator

.

White spot inverter

.

Video preamplifier with noise protection

.

Switchable AFC

.

AGC with noise gating

.

Tuner AGC output (NPN tuner for 2540)-(PNP

tuner for 2541)

.

VCR switch for video output inhibition (VCR

play back)
