#106414 - Mixing 3V and 5V chips Responding to: ???'s previous message |
Athar,
Did you pay attention to the fact that you are trying to interface a 3V ADC chip to a 5V AT89C51 microcontroller. Have you used some level translation? This document might also help. http://focus.ti.com/lit/an/slaa092a/slaa092a.pdf |
