I need a help for a circuit i can use to measure the AC 220V voltage using MCU with builtin A/D

Hehe... What's MCU

ops: ?

for Agent 009 information, MCU is microcontroller unit. Vincent, i 'm not sure if i could help, but if you want to measure the AC 220V voltage for zero crossing detection, you can look some samples at zilog website or you can serch through the net on zero crossing detection circuit.
