Voltage Feedback Rail-to-Rail Triple Amplifiers Deliver High Bandwidth with a Wide Output Swing
The ADA4855-3 and ADA4856-3 are rail-to-rail amplifiers that provide a broad output voltage range at a wide –3 dB bandwidth, allowing analog video systems to deliver cost efficient, high quality HD video for high speed video applications. Both devices have triple amplifier outputs and offer low noise, low output crosstalk, and fast overdrive recovery. With a fixed gain of 2, the ADA4856-3 provides cost and space savings for projectors, monitors, and computers that output HD video. Both devices operate on 3.3 V to 5 V supplies and are available in small 16-lead LFCSP packaging.
A number of video encoders, decoders, multiplexers, and receivers are compatiblewith the ADA4855-3 and ADA4856-3, including:
Compact Video Filter and Buffer Supports HD and SD Signals Simultaneously The ADA4420-6 is a low cost video reconstruction filter and buffer specifically designed for consumer applications. It consists of six independent filter channels: three for standard definition (Y/C, CVBS) and three for high definition component (YPrPb or RGB) signals. The device operates on a single 5 V supply, making it ideal for applications where power consumption is critical. The disable feature allows further power conservation by reducing the supply current to 10 µA (typical) when the ADA4420-6 is not in use. The ADA4420-6 operates in the extended industrial temperature range of –40°C to +85°C and is available in 20-lead TSSOP pinout and 16-lead QSOP pinout packaging. Complete Signal Chain Solution for High Resolution Video Distribution over UTP Cable ADI's extensive portfolio now supports the complete signal chain for high resolution video distribution over UTP cable. Working with a single IC supplier, designers can now realize the benefits of better part-to-part compatibility, and receive industry-leading application support and economical price points. Each component in the signal chain has unique functionality and performance advantages.
