VARIABLE Q FILTER
DESCRIPTION
The ZXF103 is a versatile analog high Q bandpass filter. It can be configured to provide pass or notch
characteristics.
The basic filter section requires 2 resistors and 2 capacitors to set the centre frequency. The frequency range is up
to 600kHz. Two external resistors control filter Q Factor. The Q can be varied up to 50.
APPLICATIONS
Many filter applications including: -
