Op Amp LF356

The Op Amp LF356 is a single operational amplifier with JFET inputs, giving it a very high input impedance and an input bias current measured in picoamps. With a 5 MHz gain-bandwidth product and a 12 V/µs slew rate, it is faster than general-purpose op-amps such as the 741 and suits precision analog work: integrators, sample-and-hold circuits, active filters and buffers for high-impedance sensors.

Op Amp LF356 Specifications

• Type: single JFET-input operational amplifier

Op Amp LF356 Applications

• Precision integrators and sample-and-hold circuits
• Active filters and audio preamplifiers
• Buffers for photodiodes, photocells and other high-impedance sources
• Fast D/A and A/D converter interfaces
• Analog electronics labs and university projects

What's in the Box

• 1 × LF356 JFET-input op-amp

Tip: The LF356 needs at least 10 V across its supply pins, so power it from ±5 V to ±15 V rather than a single 5 V rail. Its pinout matches the 741, which makes it an easy upgrade in many circuits; fit 100 nF decoupling capacitors close to both supply pins.
