Philips TDA3842
The TDA3842 is a bipolar integrated circuit for vision IF-signal processing in multistandard TV and VTRs, designed for a supply voltage range from 5.0 V to 8.0 V.FEATURES
● Low supply voltage range, from 5.0 V to 8.0 V● Low power dissipation, 200 mW at 5 V
● High supply ripple rejection
● Wide IF bandwidth of 80 MHz
● Synchronous demodulator with low differential phase and gain
● Additional video buffer with a wide bandwidth of 10MHz
● Video off switch
● Peak sync AGC for negative modulation, e.g. B/G
● Peak white AGC for positive modulation, e.g. L
