This circuit acts as a bandpass filter with gain and would be most useful for biomedical instrumen-tation. Low-frequency cutoff is set at 10 Hz while the high-frequency breakpoint is given by the openloop rolloff characteristic of the HA-5141/42/44. In this case, the AVCL= 60 dB where the rolloff occurs at approximately 300 Hz. This comer frequency may be trimmed by inserting a capacitor in parallel with Rf.
