LF156H/NOPB

Overview

The LF156H/NOPB is a single-channel JFET input operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 5 MHz and a slew rate of 12 V/us. The device operates with an input bias voltage of 2 mV and an input bias current of 100 pA. Power supply requirements range from 10 V to 44 V, with a quiescent current of 5 mA per channel. It delivers an output current of 25 mA and offers a common-mode rejection ratio of 100 dB. Input voltage noise density is 12 nV/sqrt Hz. The component is housed in a TO-99-8 package for through-hole mounting and supports an operating temperature range from -55 C to +125 C.

Feature Summary

• JFET input architecture providing low input bias current
• High common-mode rejection ratio for signal integrity
• Wide dual power supply voltage capability

Applications

• Precision instrumentation circuits
• High-speed signal processing
• Low-noise amplification stages

Procurement Notes

Verify the specific suffix H against official Texas Instruments documentation to confirm military-grade qualification or extended temperature specifications. Ensure the NOPB designation aligns with RoHS compliance requirements for your assembly process. Cross-reference the TO-99-8 package dimensions with your PCB footprint library to guarantee mechanical compatibility during installation.

Selection Notes

Select this component when low input bias current and high slew rate are critical for maintaining signal fidelity in high-frequency applications. The wide operating temperature range makes it suitable for harsh environments where standard commercial parts may fail. Consider the TO-99-8 package constraints if space is limited, as it requires through-hole mounting rather than surface-mount solutions.

Part Context

This part belongs to the LF156 series of JFET input operational amplifiers. The series is characterized by high speed and low noise performance. The LF156H/NOPB variant specifically targets applications requiring robust performance across extreme temperature conditions, distinguishing it from lower-tier commercial variants within the same family.
