LM392N

Overview

The LM392N is a dual-channel low-power comparator integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 32V and features an output current capability of 40mA at 5V. The device has a typical response time of 1.3μs, a bandwidth of 1MHz, and a slew rate of 100mV/μs. Input offset voltage is specified at 7mV with a static current consumption of 500μA. It utilizes an 8-pin MDIP package and functions within a temperature range of 0°C to 70°C.

Feature Summary

• Dual-channel configuration for independent signal comparison
• CMOS/TTL compatible open-collector outputs
• Low power consumption suitable for battery operation
• Wide single-supply voltage operational range

Applications

• Voltage monitoring circuits
• Level detection systems
• Simple analog-to-digital conversion interfaces

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the procurement channel provides traceable component history. Confirm that the package type matches the required PCB footprint specifications before finalizing orders.

Selection Notes

Select this component when a dual-channel solution is required with low quiescent current draw. It is appropriate for applications where CMOS or TTL logic interfacing is necessary without additional buffering. Consider the 1.3μs response time limitations for high-speed switching requirements.

Part Context

This part belongs to the LMx92 series of low-power comparators from Texas Instruments. It serves as a cost-effective alternative to higher-speed devices in applications where power efficiency is prioritized over rapid transition times. The PDIP-8 package facilitates through-hole mounting for prototyping and industrial equipment.

Replacement Considerations

LM393N/NOPB: Dual-channel low-power comparator with similar functionality but potentially different offset voltage specifications.
