LM393LVDSGR

Overview

The LM393LVDSGR is a dual analog comparator manufactured by Texas Instruments, designed for low-voltage applications. It operates within a supply voltage range of 1.65 V to 5.5 V and features an open-drain output type suitable for general-purpose use. The device incorporates rail-to-rail input capability and includes two channels per package. Key electrical specifications include a maximum input offset voltage of 2 mV, an input bias current of 5 pA, and a quiescent operating current of 50 uA. It provides a common-mode rejection ratio of 50 dB and a power-supply rejection ratio of 70 dB. The component is housed in an 8-pin WSON package and supports operation across a temperature range from -40°C to +125°C.

Feature Summary

• Supports low-voltage operation with a wide supply range from 1.65 V to 5.5 V
• Features rail-to-rail input capability for extended signal handling
• Provides open-drain outputs compatible with various logic families
• Delivers high precision with low input offset voltage and bias current

Applications

• Battery-powered systems requiring low quiescent current
• Threshold detection circuits in portable electronics
• Signal conditioning for low-voltage microcontrollers
• Over-voltage or under-voltage protection schemes

Procurement Notes

Verify the specific ordering suffix 'GR' corresponds to the WSON-8 package and reel packaging configuration as listed in official Texas Instruments documentation. Confirm RoHS compliance status through the manufacturer's product information page. Ensure the selected variant matches the required thermal performance for the intended operating environment. Cross-reference the Mouser part number 595-LM393LVDSGR for accurate distributor identification.

Selection Notes

Select this component when designing circuits that require dual comparators with minimal power consumption and rail-to-rail input functionality. The low input bias current makes it suitable for high-impedance sensor interfaces. Consider the WSON-8 package size for space-constrained layouts. Verify that the open-drain output configuration aligns with the pull-up requirements of the downstream logic circuitry.

Part Context

This device belongs to the LM393LV series, which focuses on low-voltage performance compared to standard comparators. Unlike the LM393ADGKR which operates at higher voltages up to 30 V, the LM393LVDSGR is optimized for modern low-power digital systems. It shares functional similarities with the LM393LVDGKR but differs in channel count and package type.

Replacement Considerations

The LM393LVDSGRG4 is a verified equivalent part number offering identical electrical characteristics and pinout compatibility. Both variants belong to the same LM393LV family and maintain functional interchangeability in existing designs.
