LM258AD

Overview

The LM258AD is a dual operational amplifier manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It features a gain-bandwidth product of 700 kHz and a slew rate of 300 mV/us. The input offset voltage is specified at 3 mV, with an input bias current of 80 nA. Operating from a single supply of 3 V to 32 V or dual supplies of ±1.5 V to ±16 V, it draws 350 uA of quiescent current per channel. The output can source up to 20 mA, providing a common-mode rejection ratio of 80 dB and an input voltage noise density of 40 nV/sqrt Hz. It supports rail-to-rail input operation within the -25 C to +85 C temperature range.

Feature Summary

Dual-channel architecture designed for low-power applications
Rail-to-rail input capability for extended dynamic range
Internal frequency compensation ensures stability without external components

Applications

General-purpose analog signal conditioning circuits
Transducer amplification interfaces
DC gain blocks in measurement systems

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official documentation. Validate datasheet revision against the specific manufacturing lot. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Evaluate thermal performance within the SOIC-8 package constraints. Compare input bias current specifications against high-impedance sensor requirements. Assess power supply rejection characteristics for noisy environments. Verify pinout compatibility during PCB layout modifications.

Part Context

This device belongs to the LM258A series, representing an improved version of the standard LM258 dual operational amplifier. The 'A' suffix indicates tighter electrical parameter tolerances compared to baseline models. The 'D' suffix designates the SOIC-8 surface-mount package variant. This component serves as a foundational building block for linear analog circuit designs requiring dual amplification stages.
