A fantastic 1500 Hz center frequency 741 active bandpass filter circuit
A fantastic 1500 Hz center frequency 741 active bandpass filter circuit. Use a dual 9 Volt Power Supply. The chip is a standard 741 IC. Lower 3DB point is around 400Hz and the upper 3DB cutoff is 5 KHz.
Replace the 1.111 K resistor with a standard 1K, the 3.537nF capacitor with a standard 3.5nF and the 31.83nF with a standard 32nF. 5% components will work just fine. A 741 Chip Pinout is shown below along with the pins on the schematic. Also included below is the setup for a dual 9V battery supply.
