MAX1416 Evaluation Kit/ Evaluation System
Evaluates: MAX1416/MAX1415/MX7705
Problem: Internal oscillator does not work.
The
Problem: Measurements are erratic or unstable or there is poor accuracy.
Check the reference voltage using a digital voltmeter. Use an oscilloscope to check for noise. When probing for noise, keep the oscilloscope
Problem: Unacceptable errors when measuring a transducer.
Although most signal sources can be connected direct- ly to the MAX1416’s analog input, some
Problem: PDA
COM ports can only be used by one device at a time. Disable PDA
