LM393ADR-EV

Overview

The LM393ADR-EV is a dual low-power voltage comparator integrated circuit manufactured by EVVO. It features a wide single-supply voltage range of 2.0 V to 36 V and a split-supply range of 1.0 V to 18 V. The device exhibits very low current drain, typically 0.4 mA, independent of the supply voltage. It provides an open-drain output compatible with DTL, CMOS, ECL, TTL, and MOS logic families. The component operates within a temperature range of 0°C to 70°C and is housed in an 8-pin SOIC package.

Feature Summary

• Dual-channel architecture integrating two independent high-precision comparators for signal processing.
• Open-drain output configuration enabling flexible interfacing with various logic levels without external pull-up requirements for low states.
• Low power consumption design maintaining minimal current drain regardless of supply voltage variations.

Applications

• Battery under-voltage protection circuits
• Zero-crossing detection systems
• Window comparator applications for high/low limit alarms

Procurement Notes

Verify the manufacturer designation as EVVO on official documentation, as the LM393 part number is widely used by multiple vendors including STMicroelectronics. Confirm the specific suffix 'ADR-EV' matches your bill of materials, as standard LM393 variants may differ in electrical tolerances or packaging specifications. Ensure compatibility with the required operating temperature range of 0°C to 70°C for your specific application environment.

Selection Notes

Select this component when a dual comparator solution is required with low static current consumption. The open-drain output necessitates an external pull-up resistor to achieve a high logic state, which allows for level shifting between different voltage domains. Verify that the input common-mode voltage range and supply voltage constraints align with the system's power rails before integration into the design.

Part Context

This component belongs to the LM series of operational amplifiers and comparators. The LM393 is a industry-standard dual comparator known for its versatility in analog signal conditioning. The EVVO variant maintains functional compatibility with established LM393 specifications while adhering to the manufacturer's specific quality and production standards.

Replacement Considerations

Publicly confirmed substitutes include the LM2903 for industrial temperature ranges and the TLV1701 for rail-to-rail input/output capabilities. Verify pinout compatibility and electrical parameter alignment before substituting these alternatives in existing designs.
