Overview
The LM393DR2GH is a dual precision voltage comparator manufactured by onsemi, housed in an 8-pin SOIC package. It supports single supply voltages from 2.0 V to 36 V and split supplies of ±1.0 V to ±18 V. The device features low input offset voltage (max 5.0 mV), low bias current (25 nA), and very low current drain (0.4 mA). It offers open-collector outputs compatible with various logic families and includes ESD protection.
Feature Summary
- Low input offset voltage specification for high-precision applications
- Wide single-supply operating range extending to 36 V
- Open-collector output compatible with DTL, ECL, TTL, MOS, and CMOS logic levels
- Input common mode range extends to ground level
Applications
- Consumer electronics
- Automotive electronics
- Industrial electronics
Procurement Notes
Verify the specific suffix 'GH' against the official onsemi datasheet to confirm exact ordering details, marking information, and shipping specifications. Ensure compliance with RoHS and Pb-free requirements as stated in the documentation. Confirm that the component meets AEC-Q100 standards if automotive application is intended.
Selection Notes
Select this component when low power consumption and wide voltage operation are required. The low input offset voltage makes it suitable for precision sensing. Verify that the open-collector output configuration aligns with the downstream logic interface requirements of the design.
Part Context
This part belongs to the LM393/LM293 family of low offset voltage dual comparators. It shares core electrical characteristics with variants like LM393DR2G but may differ in packaging or specific manufacturing site controls indicated by the suffix.
