UNISONIC TECHNOLOGIES CO., LTD V2267 LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 9 Copyright © 2009 Unisonic Technologies Co., Ltd QW-R124-006.B DUAL VIDEO 6dB AMPLIFIER WITH 75Ω DRIVER „ DESCRIPTION The UTC V2267 is a dual video 6dB amplifier with 75 Ω 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 75 Ω drivers to be connected to TV monitors directly. Further mo re 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. „ FEATURES * Dual Channel * Wide Operating Voltage (4.85V ~ 9.0V) * Low Operating Current 14.0mA (Dual) * Wide Frequency Range (7MHz) * Internal Clamp Function * Internal Driver Circuit For 75Ω Load * SAG Corrective Function * Bipolar Technology DIP-8 SOP-8 TSSOP-8 MSOP-8 Lead-free: V2267L Halogen-free: V2267G „ ORDERING INFORMATION Ordering Number Normal Lead Free Plating Halogen Free Package Packing V2267-D08-T V2267L-D08-T V2267G-D08-T DIP-8 Tube V2267-S08-R V2267L-S08-R V 2267G-S08-R SOP-8 Tape Reel V2267-SM1-R V2267L-SM1-R V2267G-SM1-R MSOP-8 Tape Reel V2267-P08-R V2267L-P08-R V226 7G-P08-R TSSOP-8 Tape Reel V2267L-D08-R (1)Packing Type (2)Package Type (3)Lead Plating (1) R: Tape Reel, T: Tube (2) D08: DIP-8, SM1: MSOP-8, S08: SOP-8, P08: TSSOP-8 (3) G: Halogen Free, L: Lead Free, Blank: Pb/Sn
