LM1458MX/NOPB

Overview

The LM1458MX/NOPB is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin SOIC surface-mount package. It features a gain-bandwidth product of 1 MHz and a slew rate of 0.5 V/µs. The device operates on a supply voltage range of 6 V to 36 V (single) or ±3 V to ±18 V (dual). Key electrical parameters include a maximum input offset voltage of 7.5 mV, an input bias current of 500 nA, and a short-circuit protected output capable of sourcing 45 mA per channel.

Feature Summary

• Short-circuit protection for output stage robustness
• Wide common-mode and differential voltage operating ranges
• Low-power consumption characteristics suitable for battery applications

Applications

• General-purpose analog signal conditioning circuits
• Transducer amplification interfaces
• Active filter implementations

Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as defined by Texas Instruments. Ensure the SOIC-8 package dimensions match the target PCB footprint. Confirm that the single-supply operation range meets the system's voltage requirements before finalizing procurement.

Selection Notes

Select this component when a dual op-amp solution with wide supply voltage tolerance is required. It serves as a direct pin-compatible alternative to the standard LM1458 series but in a surface-mount format. Consider the 1 MHz bandwidth limit for high-speed signal processing tasks where faster alternatives may be necessary.

Part Context

This part belongs to the LM1458 family of dual operational amplifiers. It shares functional similarities with the through-hole LM1458N variant but utilizes an SOIC package for automated assembly. The device is designed for general-purpose analog applications requiring reliable performance across a broad temperature range.

Replacement Considerations

The LM1458N/NOPB is a verified through-hole replacement option within the same manufacturer family.
