Low-pass filtered non-inverting amplifier circuit
CIRCUIT060057
Overview
This low-pass non-inverting circuit amplifies the signal level by 20 V/V (26 dB) and filters the signal by setting the pole at 10 kHz. Components R1 and C1 create a low-pass filter on the non-inverting pin. The frequency response of this circuit is the same as that of a passive RC filter, except that the output is amplified by the pass-band gain of the amplifier. Components C2 and R3 are used to set the cutoff frequency, fc, of the non-inverting amplifier.
