This is the fullwell curve. The fullwell is 15.5ke when zero gain. about 4ke@unity gain. Less than
100e at gain50.
10. How to protect the cooler in QHY183C?
The cooler in QHY183C can lower the CMOS temperature to a value that's almost 40 degrees
centigrade below the ambient temperature. So you need to be careful to avoid thermal shock,
which means that when the cooler's temperature rises or fall dramatically, the cooler is subjected
to strong internal stress due to contraction principle. Drastic thermal shock can shorten cooler's
service life or permanently break it.
So when you begin to adjust the CMOS temperature, you should avoid setting "Cooler Power" to
its maximum value, and you should gradually turn up the "Cooler Power" value. When you turn off
the power, if the "Cooler Power" value is very big, you should gradually turn it down before turn
off the power.
