Part Number: TLV2371-Q1
Some TLV2371-Q1's output is not good.
So I measured between positive input and negative input.
Abnormal TLV2371-Q1 is open and normal(good) one is about 930mV.
I already used upper 20K but this issue is not occurred.
Why this issue is occurred? What is checking point?
Please let me know and help me.
I attached test file.
Do you have problem with the op amp output? can you please give some more details? Where do you insert the 20K resistor? Can you please measure between each input and GND/VDD? I believe it is normal to measure certain voltage between the 2 inputs using DC meter.
Please make sure your meter probes touch the device pins

In reply to Jake Jung:
I attached test result using multimeter.
Please check this file and let me know this abnormal cause.
I asked to measure the continuity on each pin and this can be done by having the positive probe at GND and negative probe at others pins. The reading should be diode drop around 0.7V.
It is very important to explain in detail the failure mode. What is the expected output and what you are measuring? How many devices are failing in application?
