Digitally Tunable MDAC Based State Variable Filter Reference Design
TIPD160
Overview
This MDAC based state variable filter offers highly accurate digital tuning of gain, center/cut off frequency, and quality factor. This circuit provides three separate filter outputs: low pass, band pass, and high pass that can be accessed simultaneously. This circuit is suitable for a broad range of applications requiring accurate digital filter tuning from audio to industrial and more!
Features
- Contains Theory, Component Selection, TINA-TI Simulation, Measured Results, PCB Layout, Modifications
- Digitally tunable high, band, or low pass filter
- Gain range -53.13 dB to 6.01 dB
- Frequency range 1.99 Hz to 28.76 kHz
- Quality factor range 0.46 to 2.14
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
