LM258N

Overview

The LM258N is a dual operational amplifier manufactured by onsemi, designed for single or split supply operation. It features low power drain and an input common-mode voltage range that extends to the negative supply rail (ground). The device operates within a supply voltage range of 3.0 V to 32 V (single) or ±1.5 V to ±16 V (split). Key electrical characteristics include a maximum input offset voltage of 7.0 mV, an input bias current of up to 150 nA, and a typical quiescent current of 1.2 mA at 5 V. It provides short-circuit protected outputs and includes internal frequency compensation.

Feature Summary

• True differential input stage with common mode range extending to the negative supply
• Internally frequency compensated for unity gain stability
• Short circuit protected outputs
• ESD clamps on inputs for increased ruggedness

Applications

• Transducer amplifiers
• DC gain blocks
• Single supply operational amplifier circuits

Procurement Notes

Verify the specific operating temperature range and package suffix against the ordering information table in the datasheet. Confirm RoHS compliance and Pb-free status as indicated by the 'G' suffix or marking. Ensure the selected variant matches the required ambient temperature limits for the application environment.

Selection Notes

Select this component for applications requiring low power consumption independent of supply voltage magnitude. It is suitable for interfacing with standard logic systems powered by 5 V without additional supplies. Consider the LM358 series variants if a higher commercial temperature range (0°C to +70°C) is sufficient, or the LM2904 series for extended industrial ranges (-40°C to +105°C).

Part Context

The LM258N belongs to the LM258/LM358 family of dual operational amplifiers. These devices utilize circuit designs perfected for quad operational amplifiers, offering advantages over standard types in single-supply applications. The N suffix indicates a PDIP-8 through-hole package. This part is distinct from the LM358 (commercial temp) and LM2904 (industrial temp) which share similar electrical architectures but differ in temperature specifications.
