Regarding AD565

One IC of AD565 was configured in unipolar configuration and it was working with accuracy as mentioned in the datasheet.

However when same IC was configured in bipolar configuration, it gave output voltage of -4.88V and +5.12V which was out of the specified datasheet limits of accuracy.


Out of 5 IC's of AD565 that was used in the circuit, all of them worked perfectly in unipolar configuration but two of them gave the error the output voltage in bipolar configuration beyond mentioned datasheet limits.




9.95 Kilo-ohm resistor in between pin no 8 and 9 would have changed to different value leading to errors only in bipolar configuration as pin no 8 is grounded in unipolar configuration?


What is the cause and reason behind such shift in output voltage of AD565?
