    ADC0808 outputting random values

    I have interfaced an atmel 89c51 with ADC0808. Vrf+ 5v.Vref- 0v.Given the clock through uC. I have also interfaced it with max232. Done the programming so that the ADC has three inputs and uC initiates the ADC0808 and sends the outputs to serial port. Input values are converted into Decimal and...

    Problem interfacing adc0808 with 8051 in Proteus 7.1

    Problem interfacing adc0808 with 8051. I have uploaded the schematic files and hex file for 8051 also. I have set the Vref(+)=2.5 and the Vin to 2.5. In this case the ADC should have an ouptut FF. But the output is not FF. Can someone explain the reason
