LM1558H/NOPB

Overview

The LM1558H/NOPB is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin TO-99 metal can package. It features a gain-bandwidth product of 1 MHz and a slew rate of 500 mV/µs. The device operates on supply voltages ranging from 6 V to 44 V with a typical operating current of 3 mA per channel. Key electrical characteristics include an input offset voltage of 5 mV, input bias current of 500 nA, and a common-mode rejection ratio of 90 dB. The input voltage noise density is specified at 30 nV/√Hz, supporting precision analog signal processing applications.

Feature Summary

• Dual-channel architecture providing two independent high-gain internal frequency-compensated amplifiers within a single component.
• Robust power supply tolerance allowing operation across a wide voltage range up to 44 V for flexible system integration.
• Metal can packaging designed for durability and thermal stability in demanding environments.

Applications

• Precision analog signal conditioning circuits
• Industrial sensor interface modules
• Military-grade instrumentation systems

Procurement Notes

Verify the specific suffix 'H' indicates the military-grade temperature range and metal can package variant distinct from commercial plastic packages. Confirm RoHS compliance status as indicated by the '/NOPB' designation against current regulatory requirements. Ensure the ordering part number matches the exact pinout and performance specifications required for the design.

Selection Notes

Select this component when a ruggedized dual op-amp with a metal hermetic seal is required for harsh environments. Compare the 1 MHz bandwidth and 500 mV/µs slew rate against application speed requirements. Evaluate the 44 V maximum supply voltage capability against available system power rails to ensure adequate headroom for the intended signal swing.

Part Context

This device belongs to the LM1558 family of dual operational amplifiers, which are characterized by their use in high-reliability applications. The LM1558 series is often utilized where long-term stability and resistance to environmental stressors are critical, distinguishing it from standard commercial grade counterparts through its specialized packaging and testing protocols.

Replacement Considerations

The LF412MH/NOPB is identified as a similar alternative offering comparable dual-channel functionality. Verify pin compatibility and electrical parameter alignment before substitution to ensure circuit performance remains within acceptable limits.
