Hot-selling and scarce ADA4412-3ARQZ Integrated Triple Video Filter QSOP-20 spot stock

Product Descriptions

The ADA4412-3 is a comprehensive filtering solution designedto give designers the flexibility to easily filter and drive variousvideo signals, including high definition video. Cutoff frequencies of the sixth-order video filters range from 9 MHz to 36 MHz and can be selected by two logic pins to obtain fourfilter combinations that are tuned for RGB, high definition, andstandard definition video signals . The ADA4412-3 has a rail-torail output that can swing 4.5 V p-p on a single 5 V supply.

The ADA4412-3 includes an output offset voltage adjustmentfeature . Output voltage offset is continuously adjustable over aninput-referred range of ±500 mV by applying a differentialvoltage to an independent offset control input .

The ADA4412-3 can operate on a single +5 V supply as well as on ±5 V supplies. Single-supply operation is ideal inapplications where power consumption is critical . The disablefeature allows for further power conservation by reducing thesupply current to typically 10 μA when a particular device is notin use .

Dual-supply operation is best for applications where thenegative-going video signal excursions must swing at or belowground while maintaining excellent video performance . Theoutput buffers have the ability to drive two 75 Ω doublyterminated cables that are either dc-coupled or ac-coupled .

The ADA4412-3 is available in a 20-lead QSOP and is rated foroperation over the extended industrial temperature range of−40°C to +85°C .
