LM258DR2

Overview

The LM258DR2 is a dual operational amplifier from onsemi, housed in an SO-8 surface-mount package. It operates within a single supply voltage range of 3.0 V to 32 V or split supplies of ±1.5 V to ±16 V. The device features low input bias currents and a common mode input voltage range that extends to the negative supply rail. Electrical characteristics include a typical input offset voltage of 2.0 mV, a maximum power supply current of 1.5 mA at 30 V, and short-circuit protected outputs.

Feature Summary

Features true differential input stages with internal compensation for stability.
Supports both single supply and split supply operation configurations.
Includes ESD clamps on inputs to enhance device ruggedness.

Applications

Transducer amplifiers
DC gain blocks
Integrators

Procurement Notes

Verify the specific suffix 'R2' indicates tape and reel shipping configuration. Confirm the operating temperature range aligns with project requirements, as the standard LM258 variant covers -25°C to +85°C. Ensure the SO-8 footprint matches the PCB design guidelines provided in the datasheet package dimensions section.

Selection Notes

Select this component when a dual op amp requires operation down to ground potential without external biasing networks. The wide single-supply voltage capability up to 32 V makes it suitable for various industrial applications. Consider the low quiescent current for power-sensitive designs compared to older general-purpose amplifiers.

Part Context

This part belongs to the LM258 series, which utilizes circuit designs perfected for quad operational amplifiers. It serves as a dual-channel equivalent to half of an LM324 device. The series is characterized by low power drain and high common-mode rejection ratios, making it a standard choice for general-purpose analog signal processing tasks.

FAQ

Can the input common mode voltage go negative?

No, the input common mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3 V relative to the negative supply rail.
