Question - Where can I download LT's FilterCAD software?
I have been asked to use an LTC1067 universal filter building block to create a band-pass filter. The LTC1067 data sheet states:
"Choosing the proper mode(s) for a particular application is not trivial and involves much more than just adjusting the fCLK/fO ratio. Listed here are six of the nearly twenty modes available. To make the design process simpler and quicker, Linear Technology has developed the FilterCADTM for Windows design software. FilterCAD is an easy-to use, powerful and interactive filter design program. The designer can enter a few filter specifications and the program produces a full schematic. FilterCAD allows the designer to concentrate on the filter’s transfer function and not get bogged down in the details of the design."
When I search for FilterCAD on the AD website, I get no results. I find that there is a Filter Wizard available on the AD site, but I have been so far unable to convince it to select the LTC1067, nor do I know if it will do for me what LT claimed FilterCAD would do if I could get it to use the LTC1067.
Apologies for the delayed reply. I've forwarded you contact information to the engineer who can help you, and they will be contacting you soon.
