LF351M

Overview

The LF351M is a single JFET input operational amplifier manufactured by onsemi (formerly Fairchild Semiconductor). It features an internally trimmed offset voltage of 10mV and a low input bias current of 50pA. The device provides a wide gain bandwidth of 4MHz and a high slew rate of 13V/µs. It operates within a supply voltage range of ±18V, with an operating temperature range of 0°C to +70°C. The component is housed in an 8-SOP package.

Feature Summary

JFET input stage providing high input impedance
Internally compensated for stability
Low input bias and offset currents
Output short-circuit protection

Applications

High-speed signal processing circuits
Precision integrators
Sample-and-hold amplifiers
Transimpedance amplifiers

Procurement Notes

Verify the manufacturer origin, as the LF351 was originally designed by Fairchild Semiconductor. Confirm that the specific LF351M variant matches the required 8-SOP package dimensions and electrical characteristics defined in the official datasheet. Ensure compliance with RoHS standards if applicable to your project requirements.

Selection Notes

Select this component when a high-speed, low-bias current operational amplifier is required for general-purpose applications. The LF351M offers a balance of performance and cost-effectiveness. Consider the 8-SOP package size for surface-mount designs where space is limited but through-hole options are not feasible.

Part Context

The LF351 series belongs to a family of high-speed JFET input operational amplifiers. The LF351M specifically denotes the surface-mount SOP version of this widely used analog component. It is part of a lineage of devices known for their robust performance in audio and instrumentation applications.

Replacement Considerations

Compatible replacements include the LF351N (DIP package) and other generic JFET op-amps like the TL071, provided pinouts and electrical specifications align with the design requirements.
