I would like to use ATD converters for the following application: The ATD is plugged inside a computer. The input to the ATD is a set of 5V lamps. The status of the lamps (ON/ OFF) is to be captured into a database on periodic intervals. The database contains fields like lamp ID, The Status of the respective Lamp and the Timestamp. Tan anyone help me to design this circuit please?
Why and A/D converter? If you are only detecting on/off condition then the there is no need. Depending on how many lights you want to monitor, a simple vb program connected to the paralell port might do everything you need.

Thanks for your reply. But I want to extend this ON/OFF reading from switch to a Light Sensitive device. So would like to use ATD. Please help me to do this. Btw: Could you please let me know how to read the ON/OFF status using VB/ C language using Parallel Port.
