LM392MX

Overview

The LM392MX is a dual low-power operational amplifier and voltage comparator manufactured by Texas Instruments. It integrates two independent amplifiers within a single 8-SOIC surface-mount package. The device operates with a supply voltage range of 1.5V to 16V and supports an extended operating temperature range from 0°C to 70°C. Key electrical characteristics include a bandwidth of 1 MHz, a slew rate of 100 mV/µs, and a maximum output current of 40 mA at 5V. The unit features a typical input offset voltage of 7 mV and a static supply current of 500 µA.

Feature Summary

• Integrates two independent low-power operational amplifiers or voltage comparators in a compact surface-mount package
• Supports wide single-supply operation ranging from 1.5V to 16V for flexible power integration
• Provides high-speed signal processing capabilities with a 1 MHz bandwidth and 100 mV/µs slew rate
• Delivers robust load driving performance with a maximum output current capability of 40 mA

Applications

• Sensor signal conditioning and amplification circuits
• Voltage monitoring and threshold detection systems
• Low-power analog signal processing applications
• Battery-powered instrumentation requiring efficient power management

Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm exact pinout, thermal rating, and material composition. Confirm RoHS compliance status and lead-free manufacturing details directly from the manufacturer datasheet prior to procurement. Ensure the selected variant matches the required operating temperature range and package tolerance specifications for the target design.

Selection Notes

Select this component when a dual-channel solution is required for low-voltage analog signal processing or comparison tasks. Evaluate the 1.5V minimum supply requirement against system power constraints. Consider the 40 mA output drive capability for direct interfacing with moderate loads without additional buffering stages. Verify that the 8-SOIC package dimensions align with the printed circuit board layout requirements.

Part Context

The LM392MX belongs to the LM392 family of dual operational amplifiers and comparators designed for general-purpose analog applications. This series emphasizes low power consumption while maintaining adequate speed for many industrial and consumer electronics functions. The MX suffix specifically denotes the 8-SOIC surface-mount package configuration, distinguishing it from through-hole variants like the LM392N.
