AA8631

Agamem Microelectronics Inc. PRELIMINARY AA8631 LOW VOLTAGE VIDEO AMPLIFIER ■ DESCRIPTION AA8631 is a low voltage 75 ohm video driver with built-in low pass filter. It supports 3V and 5V operating voltage, and is ideal for video output device, ranging from portable digital still camera and stationary equipment such as DVD player. It incorporates high performance 4-stage LPF which is ideal for removing DAC sampling noise. In addition, ultra-low power consumption is achieved through power saving to under 1uA. It prolongs the battery life of portable device. ■ FEATURES • Operating voltage, typical 2.8~5.5V • Operating temperature range, -40~85 ℃ • Current consumption, 9.0mA typical • Current consumption during power saving, 1.0uA • High precision voltage gain, 6.0dB +/- 0.3dB • Built-in high performance 4-stage LPF, 6.75 MHz/ 100KHz Max. +1/-5dB 15 MHz/ 100KHz Typ.-25dB • Internal clamp, 1.3V • Ultra small package, SOT-26A • AC-couple or DC-couple output ■ APPLICATION • Portable • Digital camera • DVD player • Surveillance ©Copyright Agamem Microelectronics Inc. 1 www.agamem.com.tw 2008/5/5 AGAMEM MICROELECTRONICS INCOPERATION RESERVES THE RIGHT TO MAKE CHANGES WITHOUT FURTHER NOTICE TO ANY PRODUCTS HEREIN TO IMPROVE RELIABILITY, FUNCTION OR DESIGN.
