LM2907-N:LM2907-N

Matsushita-san,

I used an online Japanese/English translator to translate your question and then to provide an answer.

Thank you for your help.

We have decided to warm it to 80 degrees for 8 hours before using it. This is done because the frequency characteristics 
with respect to temperature are improved.In fact, the source of this story is unknown.I would like you to teach me, 
but is the above method actually effective?
Thank you for your answer.

Baking semiconductor devices such as the LM2907-N at elevated temperatures will sometimes relax stresses on the semiconductor die
induced by the plastic molding compound. That may affect the voltage offset of the LM2907-N comparator and operational amplifier.
This would normally happen over time in normal operation, but the baking causes it to occur more rapidly. Therefore, the device's
may exhibit less variation over time when in use.

LM2907-Nなどの半導体デバイスを高温でベーキングすると、半導体ダイへの応力が緩和されることがあります。
プラスチック成形コンパウンドによって誘発されます。これは、LM2907-Nコンパレータとオペアンプの電圧オフセットに影響を与える可能性があります。
これは通常、通常の操作では時間の経過とともに発生しますが、ベーキングにより、より迅速に発生します。したがって、デバイスの
使用中の経時変化が少ない場合があります。
