Agamem Microelectronics Inc. AA8641 LOW VOLTAGE VIDEO AMPLIFIER DESCRIPTION AA8641 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.
