Published:2009/7/24 13:09:00 Author:Jessie | From:SeekIC

This circuit shows a 12th-order filter that uses two LTC1062s and a precision dual op amp. Figure 7-16B shows the frequency response for the following values: fc=4 kHz, R=59 kΩ, C=0.001μF, R'=5.7 kΩ, C'=0.01 μF, R1=R2=39.8 kΩ, C1=2000 pF, C2=500 pF, fclock=438 kHz.
