LM258NG

Overview

The LM258NG is a dual operational amplifier manufactured by onsemi, housed in an 8-pin PDIP package. It operates from single or split power supplies ranging from 3.0 V to 32 V. Key electrical characteristics include a large DC voltage gain of 100 dB, a unity-gain bandwidth of 1.1 MHz, and low input bias current of 45 nA typical. The device features internally frequency compensation, short-circuit protected outputs, and an input common-mode voltage range that extends to the negative supply rail.

Feature Summary

• Single supply operation capability with input common-mode range extending to ground
• Internally frequency compensated for stability without external components
• Short circuit protected outputs for enhanced reliability
• True differential input stage design

Applications

• Transducer amplifiers
• DC gain blocks
• Conventional operational amplifier circuits requiring single supply implementation

Procurement Notes

Verify the specific suffix 'N' corresponds to the PDIP-8 package configuration required for your board layout. Confirm the operating temperature range aligns with your environmental specifications, as this variant supports -25°C to +85°C. Ensure compliance with RoHS standards if applicable to your manufacturing process. Cross-reference the ordering information to confirm availability and shipping quantities.

Selection Notes

Select this component when designing circuits that require dual amplification within a single supply system. It is suitable for applications needing high DC gain and wide bandwidth. Consider the PDIP-8 package for through-hole mounting requirements. Evaluate the input offset voltage and bias current specifications against your signal integrity needs.

Part Context

This device belongs to the LMx58 series of single supply dual operational amplifiers. It shares architectural similarities with quad variants like the LM324 but contains two independent high-gain amplifiers. The series is designed for cost-effective solutions in consumer and industrial electronics where power consumption and supply voltage flexibility are critical design constraints.
