10_kHz_frequency_to_voltage_convener

10 kHz frequency-to-voltage convener. The input signal should be a pulse train or square wave with characteristics similar to TTL or 5-volt CMOS outputs. Minimum pulse width is 40 μs. Full scale output is 1 volt for a 10kHz input. To trim first set Vos to midrange and trim the 2K pot for 1-volt output. Then apply a 10-hertz waveform and trim Vos for a 10 mV output (courtesy Analog Devices, Inc.).
