LM1458M/NOPB

Overview

The LM1458M/NOPB is a dual operational amplifier manufactured by Texas Instruments, featuring two independent amplifiers within a single package. It operates on a supply voltage range of 6 V to 36 V and supports a maximum dual supply of ±18 V. Key electrical parameters include a gain-bandwidth product of 1 MHz, a slew rate of 0.5 V/µs, and an input offset voltage of 6 mV. The device provides an output current of 45 mA per channel and functions within a temperature range of 0°C to 70°C.

Feature Summary

• Dual-channel architecture providing two independent operational amplifiers in one package
• Wide single-supply operation capability from 6 V to 36 V
• High output drive capacity with 45 mA per channel

Applications

• General-purpose analog signal processing circuits
• Audio pre-amplification stages
• Sensor signal conditioning

Procurement Notes

Verify the specific suffix 'M' indicates surface-mount packaging distinct from through-hole variants. Confirm the 'NOPB' designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure authenticity and correct revision level before procurement.

Selection Notes

Select this component for designs requiring dual amplification with moderate bandwidth and high output current. It serves as a direct pin-compatible replacement for legacy bipolar op-amps. Consider the 1 MHz gain-bandwidth product for applications not requiring high-speed performance. Ensure the operating environment stays within the specified commercial temperature limits.

Part Context

This part belongs to the LM1458 series, which is a dual version of the industry-standard LM1455/LM1558 family. It is designed as a drop-in replacement for older bipolar dual operational amplifiers. The device maintains compatibility with standard DIP and SOIC footprints used in established electronic designs.
