LM258DT Dual Operational Amplifier | Low Offset Voltage, Low Power, 100 dB CMRR | DIP-8 | STMicroelectronics

LM258DT

Integrating two independent high-performance operational amplifiers, the LM258DT operates over a wide voltage range of 3 V to 32 V single-supply or ±1.5 V to ±16 V dual-supply, featuring low offset voltage, high input impedance, and high common-mode rejection ratio, ideal for signal conditioning, audio amplification, current sensing, and sensor interface applications.

Product Description

Product Overview

The LM258DT is a dual operational amplifier from STMicroelectronics’ LM258 series, offering high performance with a wide operating voltage range. Each op-amp operates from 3 V to 32 V single-supply or ±1.5 V to ±16 V dual-supply, making it ideal for applications with varying power supply conditions.

With a typical input offset voltage of 2 mV and input bias current as low as 50 nA, the device provides a high common-mode rejection ratio (up to 100 dB), ensuring signal accuracy in challenging environments. It is especially suited for audio amplification, signal conditioning, current monitoring, and other high-impedance applications.
