LF351N Single JFET Op-Amp IC DIP-8

Description

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.
