Overview
The LM393EDR2G is a dual independent precision voltage comparator manufactured by onsemi, housed in an 8-SOIC surface-mount package. It operates from a single supply of 2 V to 36 V or split supplies of ±1 V to ±18 V. The device features a very low supply current of 0.4 mA and supports an input common-mode voltage range that includes ground. Electrical specifications include a maximum input offset voltage of 5 mV at 25 °C and a typical response time of 1.5 µs. It provides an open-collector output capable of sinking up to 16 mA and is rated for commercial operation between 0 °C and +70 °C.
Feature Summary
- Dual independent comparators with wide single-supply voltage range
- Input common-mode voltage range extends to ground level
- Open-collector outputs compatible with various logic families
- Low power consumption independent of supply voltage
Applications
- Limit comparators
- Simple analog-to-digital converters
- Time delay generators
- MOS clock timers
Procurement Notes
Verify the specific suffix 'E' indicates the commercial temperature grade (0°C to +70°C) distinct from other variants like 'LM293'. Confirm the 'DR2G' designation corresponds to the SOIC-8 tape and reel packaging format. Ensure compliance with RoHS standards and lead-free requirements as specified in the ordering information section of the datasheet.
Selection Notes
Select this component when dual comparators are required within a single package to save board space. It is suitable for applications needing ground-referenced sensing without dual supplies. Consider the open-collector output requirement for pull-up resistor implementation. Verify that the 5 mV maximum input offset voltage meets the precision requirements of the target circuit design.
Part Context
This part belongs to the LM393 series of low offset voltage dual comparators. It shares functional similarities with the LM293, LM2903, and NCV2903, differing primarily in operating temperature ranges and automotive qualification status. The LM393EDR2G specifically targets general-purpose commercial electronics applications requiring reliable voltage comparison.
Replacement Considerations
LM393DR2G serves as a direct substitute within the same product family.
