LM392DR2G

Overview

The LM392DR2G is a low-power operational amplifier and comparator integrated circuit manufactured by onsemi. It combines two functions within a single package: an op amp and a comparator. Both devices can operate on single-supply power with a common-mode range down to ground, and operation from split power supplies is also possible. The device features a wide power-supply range of 3 V to 32 V, low input offset voltage of 2 mV, and low quiescent current of 600 µA. The output of the comparator interfaces directly with TTL or CMOS logic.

Feature Summary

• Combines an operational amplifier and a voltage comparator in one package
• Operates on single-supply power with common-mode range including ground
• Comparator output interfaces directly with TTL or CMOS logic
• Low quiescent current suitable for portable equipment

Applications

• Level Detectors
• Voltage Controlled Oscillators
• Transducer Amplifiers

Procurement Notes

Verify the specific ordering suffix DR2G corresponds to the SOIC-8 tape and reel packaging configuration. Confirm the operating temperature range matches the commercial specification of 0°C to +70°C. Ensure compliance with RoHS standards and lead-free requirements as indicated in the datasheet documentation before finalizing procurement specifications.

Selection Notes

Select this component when a combined op amp and comparator solution is required in a compact form factor. It is suitable for applications needing direct logic interfacing without additional level shifting. Consider its low power consumption for battery-operated designs. Verify that the supply voltage range and common-mode input requirements align with the system design constraints.

Part Context

The LM392 is part of onsemi's portfolio of low-power analog mixed-signal devices. It integrates both amplification and comparison functionalities into a single SOIC-8 package. This integration reduces board space and simplifies circuit design for applications requiring both signal conditioning and threshold detection capabilities.
