FULLY BUFFERED SHARP ROLL-OFF LUMINANCE FILTER

AH847

The AH847 has been designed for filtering PAL or luminance signals in post D and A applications. The performance specification is based on the Faraday TFT range of passive filters offering good rejection at the 6.75 MHz point but sinx/x compensated for a 27 MHz sampling frequency.

Interfacing to the system is simplified with high input and low output impedance op-amp buffer stages.
