GENERAL DESCRIPTION

The ADA4420-6 is a low cost video reconstruction filter specifically

designed for consumer applications. It consists of six independent

sixth-order Butterworth filters/buffers, three for standard

definition (Y/C or CVBS) and three for high definition

component signals (YPrPb or RGB).

The ADA4420-6 operates from a single 5 V supply and has a

low quiescent current of 32 mA, making it ideal for applications

where power consumption is critical. A disable feature allows

for further power conservation by reducing the supply current

to less than 8 µA typical when the device is not in use.

Each channel features a transparent sync tip clamp, allowing ac

coupling of the inputs without requiring dc restoration.

The output drivers on the ADA4420-6 have rail-to-rail output

capabilities with 6 dB gain. A built-in offset of 250 mV allows

the outputs to be dc-coupled, eliminating the need for large

coupling capacitors. Each output is capable of driving two 75 Ω

doubly terminated cables.

The ADA4420-6 is available in either a 16-lead QSOP or a 20-lead

TSSOP, and operates in the extended industrial temperature

range of −40°C to +85°C.
