LM1458MX/NOPB

Overview

The LM1458MX/NOPB is a dual operational amplifier manufactured by Texas Instruments, continuing the National Semiconductor lineage. It features two independent high-gain amplifiers within an 8-pin SOIC surface-mount package. Key electrical specifications include a gain-bandwidth product of 1 MHz and a slew rate of 0.5 V/µs. The device operates on supply voltages ranging from 6 V to 36 V (single) or ±3 V to ±18 V (dual). Input offset voltage is typically 6 mV, with an input bias current of 500 nA. It supports output currents up to 45 mA per channel and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

Dual-channel architecture providing two independent high-gain operational amplifiers in a single compact package
Wide single-supply operation capability allowing flexibility in power system design
Standard bipolar input stage ensuring compatibility with general-purpose analog signal processing applications

Applications

General-purpose analog signal conditioning circuits
Audio pre-amplification stages
Active filter implementations

Procurement Notes

Verify that the suffix MX indicates the SOIC-8 surface-mount package variant rather than the through-hole DIP version. Confirm NOPB compliance status via the manufacturer datasheet. Ensure the supplier source is authorized to guarantee component authenticity for this specific Texas Instruments part number.

Selection Notes

Select this component when a surface-mount solution is required for dual op-amp functionality. It serves as a direct pin-compatible replacement for legacy LM1458 DIP packages in designs transitioning to SMD assembly. Consider the 1 MHz bandwidth limit for high-frequency requirements.

Part Context

This part belongs to the LM1458 family, originally developed by National Semiconductor before its acquisition by Texas Instruments. The LM1458 series is a standard dual operational amplifier widely used in industrial and commercial electronics. The MX suffix specifically denotes the small-outline integrated circuit package format.
