Overview
The LM258AMX is a dual operational amplifier manufactured by onsemi, belonging to the LM258 series. It features two independent high-gain amplifiers with internal frequency compensation. The device operates from a single power supply ranging from 3 V to 32 V or dual supplies of ±1.5 V to ±16 V. Key electrical parameters include an input offset voltage of 5 mV, input bias current of 150 nA, and a quiescent supply current of 1.2 mA per channel. It provides a short-circuit protected output capable of sourcing 30 mA. The unit utilizes an SOIC-8 surface-mount package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Single-supply operation capability allowing direct interface with standard logic systems without additional power supplies.
- Input common-mode voltage range includes ground, enabling output voltage swing to ground even in single-supply configurations.
- Internally frequency compensated for stability in unity gain applications.
- Short-circuit protection integrated into the output stage.
Applications
- Transducer amplifiers
- DC gain blocks
- Conventional operational amplifier circuits in single-supply systems
Procurement Notes
Verify the specific suffix 'MX' against the official onsemi datasheet to confirm it denotes the SOIC-8 tape-and-reel packaging variant. Confirm that the component meets RoHS compliance standards as specified in the manufacturer's documentation. Ensure the ordering information matches the exact part number to avoid discrepancies in package type or temperature rating.
Selection Notes
Select this component when a dual op-amp solution is required for single-supply applications. It is suitable for designs needing rail-to-ground input and output capabilities. Consider the 30 mA output drive and 1.2 mA quiescent current for power budgeting. Verify that the SOIC-8 package fits the PCB layout constraints and that the -40°C to +85°C temperature range meets environmental requirements.
Part Context
The LM258AMX is part of the broader LM258 family of low-power dual operational amplifiers produced by onsemi. This series is widely recognized for its ability to operate efficiently from a single power supply over a wide voltage range. The AMX designation specifically identifies the industrial temperature grade and surface-mount packaging within the product line.
Replacement Considerations
LM258N: Pin-compatible through-hole alternative from onsemi. LM258DR2G: Surface-mount replacement from onsemi in SOIC-8 package. LM258DMR2G: Surface-mount replacement from onsemi in MSOP-8 package. LM258AMDREPG4: Alternative from Texas Instruments with similar specifications.
