Hi all,
I need a circuit for converting voltage to frequency using AD537JH. Here voltage is my input signal to the ad537jh and output is in the form of frequency. When ever input voltage is zero then the AD537JH should give 10khz frequency. If the input voltage is at maximum (i.e +Ve) AD537JH should give 15khz, similarly if input voltage at minimum( i.e. -Ve) AD537JH should give 5Khz. Therefore could you suggest me the circuit diagram with AD537JH(H-10A metal cap package, 10-Pin). I have followed the datasheet. But didn't get my output, please do not suggest other V to F converters because I have already purchased AD537JH.

 

I think the data sheet is clear on how to make the AD537 work form 0 to 1V or 0 to 10V.
In your requirement does +Ve and -Ve change or are they fixed?
...I think it is simple if the input goes from -5V to +5V. But hard when +Ve can be any voltage.
Is Ve the supply voltage?
....Many op-amps will not work then the input and output are close to the supply voltage.

Thanks for the immediate reply.
Sorry, I forgot to mention that +ve and -Ve are signal at positive to negative rail ( -1V to +1 V).. supply voltages are at +5V and -5V..

Now , suggest me that how can use AD537JH as voltage (-1V to +1V) to frequency (5khz to 15khz) converter.

 

Can you make the AD537 circuit that works from 0 to 2V?
Do you understand OP-amps?
Can you make a circuit, input -1 to +1, output = 0 to 2V? Hint the gain is 1 and the offset is 1V.
