LF351N Single JFET Op-Amp IC DIP-8
Is a single-channel JFET input operational amplifier that offers extremely high input impedance and very low input bias current, which minimizes signal loading and improves accuracy in sensitive circuits. With a high slew rate and wide gain-bandwidth product, can handle fast-changing signals with minimal distortion. It operates on dual power supplies up to ±18 V, making it suitable for professional audio, instrumentation and industrial signal conditioning circuits. The DIP-8 through-hole package allows easy breadboard prototyping and permanent PCB mounting.
Features:
- Internally adjustable input offset voltage.
- Low power consumption.
- Wide common-mode (up to VCC+) and differential voltage range.
- Low input bias and offset current.
- Output short-circuit protection.
- High input impedance JFET input stage.
- Internal frequency compensation.
- Latch up free operation.
- High slew rate 16 V/µs.
