Analog Devices ADA4431-1 video filter
Thursday 5 July 2007
A video filter for driving composite video from portable multimedia devices to a TV from Analog Devices is its first to integrate a charge pump and load detect feature.
The ADA4431-1 video filter and buffer has automatic load detect to lower power consumption.
The load-detect feature lowers total system quiescent current consumption when no video signal is present.
The video filter incorporates a charge pump in place of traditional AC-output coupling, which
eliminates the capacitor to enable smaller real estate, lower cost, and more efficient design.
The ADA4431-1 is available in a lead-frame chip-scale package (LFCSP), which at 0.55mm is 35 per cent thinner than traditional LFCSP packages.
The filter offers 1dB flatness out to 5.5MHz, rejection of 28dB at 27MHz and differential gain and phase of 0.55% and 0.31 degrees, respectively.
