AH830 - Faraday Technology

AH830
FULLY BUFFERED COLOUR DIFFERENCE PREFILTER
The AH830 has been designed to provide colour difference signal filtering with a flat shape for pre
A/D applications sampling at 6.75 MHz. Interfacing to the system is simplified with high input and
low output impedance op-amp buffer stages.
