    i want to you this IC for frequency to voltage conversion....I made the entire circuit as suggested in the data sheet...but my circuit works only at 5v even then the output is saturated at 3.8 volts.
    When i am using a supply of 15v, i am getting no output...please help

    Since you just joined you may not be able to post a circuit, but maybe you can post a link to the data sheet and figure number?
