Composite Video Amplifier Output Capacitor-less Video Drivers BH76806FVM, BH76809FVM, BH76812FVM, BH76816FVM No.14064EBT02 ●Description The BH768xxFVM series video drivers are the optimum solution for high density integration systems such as, digital still cameras, mobile phones, and portable video devices. A built-in charge pump circuit eliminates the need for a large output coupling capacitor. Features include: a built-in LPF, low-voltage (2.5 V) operation, and 0 µA current consumption during standby mode. ●Features 1) Select from four video driver amp gain settings: 6 dB, 9 dB, 12 dB, and 16.5 dB 2) Large-output video driver with maximum output voltage of 5.2 VP-P Supports wide and low-voltage operation range. 3) No output coupling capacitor is needed, which makes for a more compact design 4) Built-in standby function sets circuit current to 0 µA (typ.) during standby mode 5) Clear image reproduction by on-chip 8-order 4.5-MHz LPF (Low Pass Filter) 6) Bias input method is used to support chroma, video, and RGB signals. 7) MSOP8 compact package ●Applications Mobile telephones, DSCs (digital still cameras), DVCs (digital video cameras), portable game systems, portable media players, etc. ●Line up matrix Part No. BH76806FVM BH76809FVM BH76812FVM BH76816FVM Video driver amp gain 6dB 9dB 12dB 16.5dB Recommended input level 1 VP-P 0.7 VP-P 0.5 VP-P 0.3 VP-P ●Absolute maximum ratings (Ta=25℃) Parameter Symbol Ratings Unit Supply voltage VCC 3.55 V Power dissipation Pd 0.47 W Operating temperature range Topr -40 to +85 ℃ Storage temperature range Tstg -55 to +125 ℃ * Reduce by 4.7 mW/C over 25C, when mounted on a 70mm×70mm×1.6mm PCB board. www.rohm.com © 2009 ROHM Co., Ltd.
