Optical Electronics active filter (3704 up to 5 kHz, 3705 up to 50 kHz, or 3706 up to 500 kHz) provides proper scale factor, impedance buffering, and isolation for measuring AC voltages at specific frequency. Circuit provides 100K input impedance and up to 10mA drive for 10-V meter. IC provides independent gain (scale factor or sensitivity), tuning, and Q (selectivity) adjustments.- Tuned Voltmeter, Optical Electronics, Tucson, AZ, Application Tip 10248.
