LM358A-SR

Overview

The LM358A-SR is a dual operational amplifier from 3PEAK, housed in an SOP-8 package. It operates on a supply voltage range of 3 V to 36 V with a quiescent current of 100 μA per channel. The device features a gain-bandwidth product of 0.9 MHz and a slew rate of 0.5 V/μs. Input offset voltage is limited to ±3 mV maximum, with a temperature drift of 7 μV/°C. The input common-mode voltage includes ground, and the output swings rail-to-rail. It supports an operating temperature range from –40°C to 125°C.

Feature Summary

• Rail-to-rail output capability
• Input common-mode voltage range extends to the negative supply rail
• Low quiescent current consumption of 100 μA per channel
• High electromagnetic interference rejection performance

Applications

• Power modules
• Sensor interface circuits
• Motor control systems
• Audio signal processing

Procurement Notes

Verify the specific ordering suffix 'SR' corresponds to the SOP-8 package and tape-and-reel quantity of 4000 units. Confirm the extended industrial temperature rating of –40°C to 125°C matches the design requirements. Ensure compatibility with RoHS and halogen-free manufacturing standards specified by the manufacturer.

Selection Notes

Select this component for applications requiring wide single-supply operation up to 36 V and low power consumption. The rail-to-rail output and ground-referenced input simplify single-supply circuit designs. Verify that the 0.9 MHz bandwidth and 0.5 V/μs slew rate meet the signal frequency and speed requirements of the target application.

Part Context

This part belongs to the LM321A/LM358A/LM324A series of high-supply voltage amplifiers manufactured by 3PEAK. The series utilizes proprietary design techniques to achieve stable frequency response and low offset characteristics. The LM358A variant specifically provides two independent amplifiers within a single package.

Replacement Considerations

The datasheet indicates these devices can serve as plug-in replacements for commercially available op amps to reduce power and improve performance. Specific substitute part numbers are not listed in the provided documentation.
