LM211DG4

Overview

The LM211DG4 is a single-channel analog comparator manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 3.5 V to 30 V and consumes 6 mA of quiescent current. The device features a differential input type with open collector and emitter outputs capable of sourcing 50 mA per channel. Key electrical specifications include an offset voltage of 3 mV, an input bias current of 75 nA, and a response time of 115 ns. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Supports both open collector and open emitter output configurations for flexible logic interfacing.

Applications

• General-purpose analog signal comparison
• Voltage monitoring circuits

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's datasheet to confirm lead-free compliance status. Ensure the SOIC-8 package dimensions match the target PCB footprint requirements. Confirm that the operating temperature range meets the environmental conditions of the intended application before finalizing procurement.

Selection Notes

Select this component when a single differential comparator with low offset voltage is required. The dual-output capability (open collector/emitter) allows compatibility with various logic families. Consider the 115 ns response time for speed-sensitive applications. Verify power supply constraints align with the 3.5 V to 30 V operational range.

Part Context

This part belongs to the LM211 series of high-speed comparators from Texas Instruments. It shares functional similarities with the LM111 and LM311 series but offers specific performance characteristics tailored for general-purpose applications. The DG4 suffix indicates a tape-and-reel packaging format compatible with automated assembly processes.
