Hi Technical Support Team,
When the TL062CP is used on high humidty(keeping 90%RH).
it causes increasing bias current(uA) during increasing temperature(30℃→85℃ / temperature slope: 0.5℃/min) with ±5V supply voltage.
If reaching 85℃/90%RH and after a period of time , bias current is stable(inside datasheet IIB specification)
On the other hand, when supply voltage is ±12V, it works well(normal bias current) with above humidty and temperature condition.
Just temperature control for 30℃→85℃(temperature slope：0.5℃/min) and not control humidty, it doesn't cause increasing leak current.
■condition
Power Supply = ±５V
Input Voltage＝０V～-３V
Opeamp setting: Voltage Follower
※Acording to datahseet, Vcm is ±1V when Power Supply is ±５V.
■Questions
1.) Does TL062CP have humidty specification? Is it possible for TL062CP to cause high bias current on high humidty condition?
2.) If input voltage is over Vcm(Vcm=±1V, but input voltage -3V), is it possible for TL062CP to cause high bias current?
I think that high humidity is not good condition for TL062CP and input voltage is over Vcm does not guarantee correct behavior.
Best Regards,
y.i
