How to know opamp burn out? (ad8009)

I am using more than 400 pieces of ad8009 in the circuit. However, it is impossible to determine if the chip is broken. The signal I get experimentally has a 4 V bias voltage. (Output pin) However, the output without a signal has a different bias. Another problem is that there is amps that works normally if i proceed with the next experiment. Circuits incorporate all voltage pins and use + 5 V and - 5 V.
