VARIABLE Q FILTER
ZXF103
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: -
• Sonar and Ultrasonic Systems
• Line frequency notch
• Signalling
• Motion detection
• Instrumentation
• Low frequency telemetry
FEATURES AND BENEFITS
• Centre Frequency up to 1MHz
• Variable Q up to 50
• Low distortion
• Low noise
• Low power 25mW
• Devices easily cascaded
• Small QSOP16 package
