    Hi,

    Does anyone here can provide me a schematic diagram of the application of VFC LM331 in "Basic Analog-to-Digital Converter using Voltage-to-Frequency Converter" in page 11 inside the datasheet ? What IC should i use for the counter and latch? Could it be 74LS90 and 74HC4511?
    Also from the datasheet the data output is connected to the computer. What if i wanted to show it in 7 segment display?
    Please assists me. Thanks.

    The datasheet can be found in the link as below

    Here is a link to a frequency counter that has 7 segment displays - http://members.shaw.ca/roma/fc.html Using "frequency counter circuit" as a search term brings up many more.
