Hello, all
Now we have one inquiry regarding output voltage range on OPA2277UA from our customer.
They are using this device on following conditions.
V+(8pin) = +12V, V-(4pin) = -12V applied.
Input voltage range between +In B (5pin) and -In B (6pin) is -5 to +5V. (using 10kohm resistor)
Output voltage from Out B (7pin) will input into -In A (2pin), +In A (pin3) is connected to GND. (Voltage follower configuration)
On above configuration which aims to output -5 to 5V from Out A (pin1), some parts on our board actually output -12 to +12V.
Please help us to find out which on above could make some this kind of issue.
We thank you in advance for your information.
Best regards,
