Product Overview
National Semiconductor LF357N monolithic JFET-input operational amplifier in an 8-pin plastic DIP package. Engineered with BI-FET technology, this single-channel op-amp provides high-speed operation, low input bias currents, and wide bandwidth for analog signal processing, precision amplification, and high-frequency circuit designs.
Key Features
- 50 V/µs typical slew rate
- 20 MHz gain bandwidth product
- 10¹² Ω input impedance with JFET front end
- 30 pA typical input bias current
- ±5 V to ±18 V dual power supply operating range
- Standard 8-pin dual in-line package (PDIP-8)
Applications
- High-speed integrators, sample-and-hold circuits, and fast D/A converters
- Audio preamplifiers, active filters, and precision instrumentation amplifiers
- Benchtop prototyping, circuit repair, and DIY analog synth or audio synthesizer builds
Frequently Asked Questions
What package type is this operational amplifier?
This is a standard 8-pin plastic dual in-line package (PDIP-8) suitable for breadboards, sockets, or through-hole PCB assembly.
Is this a compensated or decompensated op-amp?
The LF357 is a decompensated wideband version designed for stable operation at closed-loop gains of 5 or greater, providing faster slew rates and higher bandwidth than internally compensated variants like the LF356.
Why buy a single piece instead of a bulk surplus lot?
Buying an individual part lets you get the specific vintage component needed for a repair or build without taking on excess inventory. Orders ship for an $8 flat rate, ship free over $28, and dispatch from our Idaho warehouse the same or next business day.
Fast analog circuits rely on steady front-ends, and this classic BI-FET op-amp is ready to drop right into your next audio or instrumentation build.
