Frequently Asked Questions
What makes a JFET-input op amp different?
JFET inputs provide very high input impedance and low bias current, making them ideal for circuits that interface with high-impedance signal sources.
Is this a single or dual op amp?
The LF356N is a single operational amplifier in an 8-pin DIP package.
Is this suitable for audio applications?
Yes. The LF356N is commonly used in audio preamps and active filters due to its low noise and high input impedance characteristics.
Can it replace other JFET op amps?
It can often substitute in circuits designed for similar single JFET-input op amps, provided the electrical specifications match the original design requirements.
When a circuit calls for a JFET front end and a classic DIP footprint, the LF356N delivers the clean analog behavior engineers have trusted for decades.
