(OP)
Hello,
we are using a Texas Instruments ads7869 Analog to Digital converter chip for a VFD control. It is used to read the motor currents. The chip has also a D/A converter that makes a reference voltage for the overcurrent comperators. The value of this D/A converter changes its value from time to time by its own, especially at cold temperatures.
Had anyone the same problems with that chip?
Kind Regards
Phaneas
