LM258DGKR

Overview

The LM258DGKR is a dual operational amplifier manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It features a gain-bandwidth product of 700 kHz and a slew rate of 300 mV/us. The input offset voltage is 5 mV, with an input bias current of 150 nA. Operating on a single supply from 3 V to 32 V or dual supplies from ±1.5 V to ±16 V, it draws 350 uA of quiescent current per channel. Each output can source 20 mA, providing a common-mode rejection ratio of 80 dB and an input voltage noise density of 40 nV/sqrt Hz.

Feature Summary

• Dual high-gain operational amplifier architecture
• Rail-to-rail input capability
• Wide single-supply voltage operation range

Applications

• General-purpose signal conditioning circuits
• Transducer amplifiers
• Buffer stages

Procurement Notes

Verify the specific suffix DGKR against the manufacturer's official datasheet to confirm the VSSOP-8 package type and tape-and-reel packaging configuration. Ensure the component meets the required industrial temperature specifications for your application environment before finalizing procurement orders.

Selection Notes

Select this component when a dual-channel solution with rail-to-rail inputs is required within a compact surface-mount footprint. Consider the 700 kHz bandwidth and 300 mV/us slew rate for moderate-speed applications. Verify that the 20 mA output drive capability meets load requirements compared to higher-drive alternatives.

Part Context

This device belongs to the LM258 series of dual operational amplifiers from Texas Instruments. It serves as a general-purpose analog signal processing component designed for cost-sensitive and space-constrained electronic designs requiring reliable amplification across a wide voltage range.
