Four Analog inputs
•
Input range 0..3.3V
•
Internal low pass RC filter (24

•
12-Bit ADC. Analog signals are
Sampled
at 1KHz. Each ADC
Sample
is average of 4 consecutive (2µs apart) samples
•
ADC
raw
is average of 1 to 64 (user selectable) most recent
Samples
.
•
For example
n=1
displays the most recent sample and
n=8
displays average of the most recent 8 samples
•
Analog signals can be converted to any unit using
