Typical applicaTions
the 2 op amp loop to create a negative summing junction
at A1’s positive input
center frequency and Q, which are set with the following
equations:
where:
The DC bias applied to A2 and A4, half supply, is not needed
when split supplies are available. The circuit swings rail-
to-rail in the passband making it an excellent anti-aliasing
filter for ADCs. The amplitude response is flat to 1kHz then
rolls off at 80dB/decade.
