    accuracy of a F/V converter

    Hi, I am using an F/V converter VFC32KP from TI. The converter is highly linear and the linearity error is 0.01%.At zero frequency the output should be at a max of 4mv according to datasheet. The problem, is it is going upto 16mv, even after trimming with a pot of 100Kohms.Can anyone suggest...

    Lowpass filter design

    I have designed a low pass butterworth flter(4th order) for a cut off freq. of 10Hz. Taking care that the gain of the filter should be -80db/decade.I am using a JFET opamp TL064. The problem is, I get the gain in postive and the signal isn't attenuated.I have designed also the passive...

    Digital potentiometer

    yea it is a divider the adjust the frequency, but the feed back is not the comparator instead to the F/V converter. Thanks Senthil

    Digital potentiometer

    Hi, Is it possible that a digital potentiometer can serve as a feed back element in a frequency to voltage converter loop. I do convert the Analog signal(5v) from the F/V in to a digital one through a comparator (the other input is from a high precision voltage reference of 5v). Can u make a...

    frequency to voltage conversion

    hello Ve7brz, Thanks for the reply. yes I need to control the frequency that I'm measuring. The freq is the output from the sensor interface connnected to a AC motor.What element must be incorporated in the feedback loop of thr F/V converter so that I can control the frequency. Thanks Senthil

    frequency to voltage conversion

    hello, I am doing a freq-voltage conversion. But need to design a feedback element in the design loop(f/v converter)to control the frequency. Do anyone have suggestion?. Is there any realisation software to check a digital output(after converting 0-10v to required digital signal through DAC)...
