LM258H/NOPB

Overview

The LM258H/NOPB is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin TO-99 metal can package. It operates on a single supply voltage ranging from 3 V to 32 V or dual supplies of ±1.5 V to ±16 V. The device features a gain-bandwidth product of 1 MHz and a slew rate of 0.3 V/µs. It draws 1 mA of supply current per channel and provides a maximum output current of 40 mA. The input offset voltage is typically 2 mV with an input bias current of 45 nA. It supports a wide operating temperature range from -25°C to +85°C.

Feature Summary

• Dual-channel architecture providing two independent general-purpose amplifiers within a single component.
• Robust TO-99-8 metal can packaging designed for high reliability and through-hole mounting.
• Capable of direct coupling with zero external components due to internal frequency compensation.

Applications

• Industrial control systems requiring reliable analog signal processing
• Sensor interface circuits for transducer signal conditioning
• General-purpose analog computation and buffering applications

Procurement Notes

Verify the specific suffix 'H' indicates the military-grade or enhanced performance variant compared to standard commercial versions. Confirm the TO-99-8 metal can package matches your PCB footprint requirements. Ensure the supplier provides traceability documentation if the application demands strict quality standards. Check RoHS compliance status as indicated by the NOPB suffix against environmental regulations.

Selection Notes

Select this component when high reliability and radiation hardness are required, as suggested by the TO-99 metal can construction. Compare the 1 MHz bandwidth against higher-speed alternatives if signal fidelity at elevated frequencies is critical. Evaluate the 40 mA output drive capability against load requirements to ensure sufficient margin for downstream circuitry.

Part Context

This part belongs to the industry-standard LMx58 family of dual operational amplifiers produced by Texas Instruments. It shares functional similarities with the LM158 and LM358 but distinguishes itself through the hermetic metal can package suitable for harsh environments. The series is widely recognized for its stability and ease of use in general-purpose analog applications.
