3.2 Connecting Pressure Sensor Amplifiers
3.2.1 FT40
The input signal from the pressure sensor amplifier is connected to pins 5 (A-FB) and 16 (SG)
on the I/O signal connector (CN1).
The input specifications are as follows:
•
Maximum input voltage:
±
12 V
•
Input voltage resolution:
±
10 bits
•
Input impedance: 30 k
Ω
Implement the following countermeasures against noise to prevent inductive noise.
•
Use twisted-pair cables.
•
Minimize the connection distance.
•
Attach a ferrite core.
Recommended Pressure Sensor Amplifier Specifications
