Forum Post: ADS8332 does not do conversion

Hello,

I need a bit of a help with  ADS8332. It is set to 0x7FD (no AUTO_CHANNEL, no TAGS) and communicates with processor (ATmega128, 20 MHz) just fine. Some time ago I've noticed that sometimes the chip suddenly switches into a mode when it stops doing conversions -  after CONVRT goes down EOC stays high and no conversion takes place, chip returns zeros (see diagram). CFR reads the same. Power cycle was bringing the chip out of this state.

Now power cycle does not help any more, chip communicates with processor fine but not doing conversions. 

Any suggestion would be appreciated,

Thanks,

Alexander.
