Analog Inputs
The Evaluation Board has 8 analog inputs. The corresponding
connector is J4 (screw terminals on the upper right).
Figure 18: Area of the analog inputs
with the associated potentiometers and the solder positions for adjustments
The analog reference voltage is 5 V. The input impedance is 6.5 k
(3.2 k
analog input microcontroller, 3.3 k
series impedance in
front of the microcontroller input).
The Evaluation Board has 4
potentiometers
(P0 to P3) which can be
used for simulating input signals. With solder jumpers on positions
JP17 to JP20 the potentiometers are connected to Ain0 to Ain3
(delivery status: closed = connected).
For
external sensors
the screw terminals provide the supply
positions AGND and AVCC.
