V2267

UNISONIC TECHNOLOGIES CO., LTD V2267 DUAL VIDEO 6dB AMPLIFIER WITH 75Ω DRIVER DIP-8 DESCRIPTION The UTC V2267 is a dual video 6dB amplifier with 75Ω drivers for SVHS VCRs, HI-BAND VCRs, etc. Its operating supply voltage is 4.85 to 9V and bandwidth is 7MHz. Each channel has clamp function that fixes DC level of video signal and 75Ω drivers to be connected to TV monitors directly. Further more it has SAG corrective circuits that prevent the generation of SAG with a small capacitance. It is for VCR, Video Camera, TV, Video Disc Player.
