It seems im having some problem with the ADT7410 on high temp.
My pcb is an a climate chamber cycling between 25 to 125 °C (4 hours ramp up)
It seems everything is going wel and i can read out temperature until +110°C... then the sensor is outputting rubbish
(even the signed bit is becomming one)
Did someone ever encounter this behaviour?
My sensor is in continous comparator mode!
I already tried
- reduce I2C clock to 2Khz
- I2C communcation (with scope) seems to be ok until high temp
- reset and reconfig on every temp readout
