LM392N/NOPB

Overview

The LM392N/NOPB is a dual operational amplifier and comparator integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 3V to 32V, supporting both single and dual power configurations. The device features two independent channels housed in an 8-pin PDIP package with through-hole mounting. Key electrical specifications include a typical response time of 1.3μs, a bandwidth of 1 MHz, and a conversion rate of 100 mV/μs. It draws a static current of 500 µA and provides an output current capability of 40mA at 5V. The input offset voltage is specified at 7 mV, and the unit functions reliably across an operating temperature range of 0°C to 70°C.

Feature Summary

• Combines dual operational amplifiers and comparators in a single low-power package
• Supports flexible single or dual power supply operation up to 32V
• Provides CMOS/TTL compatible outputs for direct logic interfacing

Applications

• General-purpose analog signal comparison and processing

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official datasheet specifications. Confirm the package type is PDIP-8 and ensure the suffix NOPB indicates lead-free compliance. Cross-reference the part number with Texas Instruments documentation to validate the active status and specific electrical tolerances before integration into production designs.

Selection Notes

Select this component when a design requires both amplification and comparison capabilities within a single low-power channel. It is suitable for applications needing a wide supply voltage range and standard through-hole packaging. Consider the 1.3μs response time and 1MHz bandwidth to ensure compatibility with the required signal frequencies and switching speeds.

Part Context

This device belongs to the LM392 family of mixed-signal integrated circuits from Texas Instruments. It integrates linear amplifier stages with digital comparator outputs, offering a compact solution for hybrid signal processing tasks. The PDIP-8 form factor facilitates easy prototyping and insertion into legacy or standard printed circuit board layouts designed for through-hole components.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives. Verify that any replacement maintains the same supply voltage limits, output drive capabilities, and thermal performance characteristics.
