Ordering number : EN5110 Monolithic Linear IC LA7425 NTSC Format Single-Chip Signal Processing IC for VHS VCR Products Overview The LA7425 is a single-chip video signal processing IC for use in VHS format VCR products. The number of required adjustments has been reduced to a single adjustment by IC chip internal trimming. The incorporation of a playback equalizer and other circuits on chip provides a significant reduction in external components and thus significantly reduces the cost of manufacturing the signal processing printed circuit board. This product can also support simplified S-VHS playback, which is becoming a standard feature in VCR products in the Japanese market.
