Description

The MAX7481/MAX7482 bidirectional video filters/buffers provide the reconstruction filter and line drive buffer for both composite (CVBS) and S-Video (Y/C) video signals in playback mode, and anti-aliasing in record mode for portable media devices. Each channel consists of a lowpass filter and an output buffer capable of driving a full 2VP-P video signal into one standard 150 load (DC-coupled to ground). In record mode, the MAX7481/MAX7482 output buffers have a gain of +6dB. In playback mode, the MAX7481 output buffers have a gain of +6dB and the MAX7482 output buffers have a gain of +7dB. The MAX7481/MAX7482 feature DirectDrive™ by utilizing an internal negative charge pump and regulator to maintain the output blanking level at ground, eliminating the need for a negative supply voltage, a large output coupling capacitor, or a sag correction configuration. The MAX7481/MAX7482 operate from a single +2.7V to +3.6V power supply. These devices are available in a space-saving 28-pin TQFN package and operate over the -40°C to +85°C extended temperature range.
