OVERSAMPLED PRE FILTER

FULLY BUFFERED HYBRID COLOUR DIFFERENCE AH852

The AH852 is a tightly specified anti-aliasing video filter for use in oversampled colour difference applications. The nti-aliasing video filter has been optimised with an accurate factory-set gain of 6dB. Use of  the latest operational amplifiers results in low current consumption and good differential phase and gain performance.

The AH852 has been designed to provide flat response filtering for oversampled colour difference applications. Interfacing to the system is simplified with high input and low output impedance op-amp buffer stages.
