The IN0 pin of ADC0808 shows 2.5volts with no connection to the sensor.

Kumara Guruparan

Hi,

i have interfaced ADC0808 with AT89c51 and i m surprised to see the IN0 pin of ADC shows 2.5V. I have not connected any sensor to it.

I like to know whether it usually shows this voltage or is there any problem with my circuit.

Moreover i see the digital values toggling randomly from 0-255 and if i ground that pin it shows 114.

can anybody help me rectifying this problem.
