App note: Filtering 101 whiteboard series

Posted on Sunday, February 10th, 2013 in app notes by DP

Here’s a series of video tutorials on filtering from Analog Devices. First in the series (embedded above) covers simple single pole filters made out of resistors and capacitors. The series moves onto active filtering with op-amps, and finishes with multi-pole Sallen-Key filters. Geek alert: theory and math zone!

  • Drone: So these go for around $330 USD and NO published calibration procedure online or otherwise? Given what's inside - I don't think I'll be considering...
  • Pekka Akselin: This is ridiculous!? :-) We are back at 256(!) byte EPROMs that needed multiple, a handful, of voltages to run! :-(
  • KH: Let's try a back-of-envelope calc balancing energies. From MCP1700 datasheet, there are graphs for a 200mA load step. Estimate the energy shortfall as 12uJ. Say...
  • Daniel: It's been a week and my comment is still awaiting moderation. Apparently the CIA doesn't want their involvement known?
  • KH: Agree, so okay, I guess he must have learned from somewhere. 100nF and 1000uF is so far apart, that was jarring; it's more magic incantation...
