Note 1: The quantities per board all have been multiplied by 4 because there are four Active 

Filter Section PCB’s (sub-assembly) in the Active Filter Demo Board Kit (assembly).

2: This part is also found at Digi-Key (ED90069-ND).
3: The components listed in this Bill of Materials are representative of the PCB 

assembly. The released BOM used in manufacturing uses all RoHS-compliant 
components.

These op amps are supplied by Microchip; they are found in the Accessory Bag 
described in Table B-5. Other op amps are supplied by the user.

2: Op amps in SOIC-8 package are supplied by the user, if desired. See ”4.6 “Using 

8-Pin SOIC Op Amps” for information on using op amps in these packages (150 
mil wide).

3: The resistors and capacitors represented by Z

 are provided by the 

customer. Not all of these will be populated for any given filter. The Accessory Bag  
described in Table B-5 includes 10 jumpers that can be used to configure different 
filter circuits.
