LF351DT

Overview

The LF351DT is a single wideband JFET input operational amplifier manufactured by STMicroelectronics. It features a gain-bandwidth product of 4 MHz and a typical slew rate of 16 V/µs. The device operates with a supply voltage range of 6 V to 32 V (dual ±3 V to ±16 V). Key electrical parameters include an input bias current of 200 pA, input offset voltage of 10 mV, and output short-circuit protection. It is housed in an 8-SOIC surface-mount package.

Feature Summary

• High-speed JFET input stage providing high input impedance
• Internally frequency compensated for stability
• Output short-circuit protection included
• Latch-up free operation

Applications

• Wideband amplification circuits
• Signal conditioning systems
• Buffer applications requiring high input impedance

Procurement Notes

Verify the specific suffix 'DT' corresponds to the tape and reel packaging format as indicated by distributor listings. Confirm RoHS compliance status through official STMicroelectronics documentation or the component datasheet before integration. Ensure the operating temperature range aligns with industrial requirements.

Selection Notes

Select this component when a single-channel op-amp with JFET inputs is required for high-speed signal processing. The 4 MHz bandwidth and 16 V/µs slew rate suit moderate-frequency applications. Consider the 8-SOIC package constraints for PCB layout. Verify power supply compatibility within the specified voltage limits.

Part Context

This part belongs to the LF351 series of high-speed operational amplifiers. It is a single-channel variant designed for general-purpose analog signal processing tasks where low input bias current and high input impedance are critical performance factors.

Replacement Considerations

Check for pin-compatible alternatives within the same family if different packaging options are needed. Verify that substitute components maintain equivalent slew rates and bandwidth specifications for direct functional replacement.
