ZXF36L01 Datasheet, PDF (1/12 Pages) Zetex Semiconductors – VARIABLE Q FILTER

ZXF36L01
VARIABLE Q FILTER
DESCRIPTION
APPLICATIONS
The ZXF36L01 is a versatile analog high Q bandpass Many filter applications including: -
filter. The device contains two sections:
• Audio bandpass and notch
1
Variable Q bandpass filter.
2
Mixer block.
• Micro controlled frequency
• Adaptive filtering
The basic filter section requires 2 resistors and 2 • ^{Sonar and Ultrasonic Systems}
capacitors to set the centre frequency. The filter _• Instrumentation
operates up to a frequency of 150kHz. Two external
resistors control filter Q Factor. The Q can be varied up
to 50.
FEATURES AND BENEFITS
The mixer is included to extend the frequency range up ^{• Centre Frequency up to 700kHz}
to 700kHz and to permit the centre frequency to be • Tuneable centre frequency
tuned. The local oscillator can be any waveform, _{• Variable Q}
making microprocessor control convenient.
• Low power
• Standby mode for improved battery life
