LF356M/NOPB

Overview

The LF356M/NOPB is a single JFET-input operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 5 MHz and a slew rate of 12 V/µs. The device operates on a supply voltage range of 10 V to 36 V (±5 V to ±18 V). Key electrical parameters include an input bias current of 200 pA, an input offset voltage of up to 10 mV, and a common-mode rejection ratio of 80 dB. It is housed in an 8-pin SOIC package with an operating temperature range from 0°C to +70°C.

Feature Summary

• Integrates matched high-voltage JFETs with standard bipolar transistors for low noise performance
• Designed for fast settling time and wide bandwidth applications
• Capable of driving large capacitive loads without stability issues

Applications

• Signal processing circuits
• Low-noise preamplifiers
• High-speed integrators

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and halogen-free compliance as per manufacturer standards. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the commercial temperature grade (0°C to +70°C) aligns with your system's thermal environment. Cross-reference the datasheet revision date to ensure parameter accuracy.

Selection Notes

Select this component when a balance between low input noise and high speed is required. The JFET input stage offers higher input impedance compared to bipolar counterparts. Consider the 12 V/µs slew rate for moderate-speed signal conditioning tasks. Evaluate the 5 MHz bandwidth against your signal frequency requirements to prevent distortion.

Part Context

This part belongs to the LF356 family of monolithic JFET-input operational amplifiers. It serves as a surface-mount variant of through-hole versions like the LF356N. The series is designed to replace expensive hybrid FET op-amps while providing robust performance in analog signal chains.

Replacement Considerations

Public confirmed substitutes include the LF356N/NOPB for through-hole compatibility and the LM356 for pin-compatible alternatives. Verify that any replacement maintains the same JFET input architecture and electrical specifications.
