Overview
The LM1458N/NOPB is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin MDIP package for through-hole mounting. It operates within a supply voltage range of -18 V to +18 V (or 6 V to 36 V single supply). 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 features an input bias current of 200 nA and supports a common-mode rejection ratio between 70 dB and 90 dB. It functions reliably across a temperature range of 0°C to 70°C.
Feature Summary
- Dual-channel architecture providing two independent high-gain internal frequency-compensated amplifiers
- Wide single or dual power supply operation capability
- Internal frequency compensation ensures stability without external components
Applications
- General-purpose signal conditioning circuits
- Active filter designs
- Transducer amplification systems
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the package type matches the required MDIP-8 footprint for PCB layout. Ensure the operating environment stays within the specified 0°C to 70°C industrial temperature range. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a dual op-amp solution is required for general-purpose analog applications. It is suitable for designs needing moderate bandwidth and standard precision levels. Consider the 8-pin DIP package for prototyping or legacy board replacements. Evaluate if the 1 MHz bandwidth and 0.5 V/μs slew rate meet the signal processing requirements.
Part Context
The LM1458 series is part of Texas Instruments' lineup of dual operational amplifiers. The LM1458N/NOPB represents the commercial grade version with enhanced specifications compared to the basic LM158. It serves as a robust alternative for applications requiring dual amplification channels in a compact through-hole package.
Replacement Considerations
LM158N/NOPB: Pin-compatible alternative with potentially different temperature or performance grades. Verify datasheet specifications before substitution.
