ACCESSORY BAG (SUB-ASSEMBLY #: 110-00097R1)
See Figure 3-1 for the circuit diagram supported by this Accessory Bag. This filter is a
Bessel low-pass with n = 5, f

C
= 100 Hz, and Gain = 1 V/V. It uses single supply,
Sallen-Key sections.
See Section B.3 “Accessory Bag BOM” for the Bill of Material for this filter. These
components are placed in an ESD separate ESD bag. The Accessory Bag includes
more MCP6271 op amps than needed for Figure 3-1; there are enough to populate all
of the DIP-8 sockets in the Active Filter Demo Board Kit. These op amps are included
in the accessory bag for ESD protection.
