Frequently Asked Questions
What power supply ranges are supported by these amplifiers?
They support both single supplies (+3 V to +30 V) and split supplies (±1.5 V to ±15 V).
What safety precautions should I take concerning short circuits?
Short-circuits can cause excessive heating, and simultaneous short-circuiting on all amplifiers can result in destructive dissipation.
How should an input driven negative be protected?
The junction base/substrate of the input PNP transistor must be protected by a resistor in series with the inputs to limit current (R = (Vin - 32 V)/400 µA).
What is the typical input bias current?
At room temperature, the typical input bias current is 20 nA.
