Frequently Asked Questions
What is the primary intended use of this amplifier?
It is designed primarily for low level audio and general purpose applications with high impedance signal sources.
How should I handle thermal dissipation above 25°C?
Use the derating factor: 5.0 mW/°C (or 2.8 mW/°C depending on required rating).
Are these rated limits for continuous use?
No, these are steady state limits. The factory should be consulted for pulsed or low duty cycle operations.
What kind of voltage breakdown is permitted?
The provided data shows a Drain-Gate Voltage (DG V) maximum rating of 40V and a Gate-Source Voltage (GS) maximum rating of -40V.
