LMV393IDRG4

Overview

The LMV393IDRG4 is a dual general-purpose analog comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and consumes a typical operating current of 200 uA. The device features an open collector/open drain output type capable of sourcing up to 23 mA per channel. Key electrical parameters include a response time of 200 ns, an input offset voltage (Vos) of 7 mV, and an input bias current (Ib) of 250 nA. It supports a common-mode voltage down to -100 mV and functions reliably across a temperature range of -40°C to +125°C. The component is housed in an SOIC-8 surface-mount package.

Feature Summary

• Dual-channel architecture designed for general-purpose signal comparison tasks
• Low-voltage operation capability supporting single-supply systems from 2.7 V
• Open collector/drain output configuration allowing flexible logic interfacing
• Extended industrial temperature rating ensuring stability in harsh environments

Applications

• Battery-powered portable devices requiring low quiescent current
• Threshold detection circuits for voltage monitoring
• General-purpose signal conditioning and waveform generation

Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to lead-free and RoHS-compliant manufacturing standards as defined by Texas Instruments. Confirm that the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the open-drain output configuration aligns with your downstream logic level requirements, as external pull-up resistors may be necessary depending on the application voltage.

Selection Notes

Select this component when a dual comparator with low power consumption is required for low-voltage applications. The LMV393IDRG4 offers a balance between speed and power efficiency suitable for battery-operated equipment. Consider the 200 ns propagation delay and 7 mV offset voltage specifications against your signal integrity needs. The wide operating temperature range makes it suitable for industrial applications where thermal stability is critical.

Part Context

This part belongs to the LMV393 series of low-voltage dual comparators from Texas Instruments. It shares functional similarities with other members like the LMV393IPWRG4 but differs in packaging, utilizing the SOIC-8 form factor instead of TSSOP-8. The series is designed to replace older bipolar comparators in modern low-voltage designs, offering improved power efficiency while maintaining compatibility with standard logic families through its open-collector outputs.
