What are the key features of LM392N?
- Dual op-amp and comparator in a single DIP-8 package — reduces BOM count in mixed-signal designs
- Low input bias current (0.25µA typ) minimizes signal loading for high-impedance sensor interfaces
- 65dB minimum CMRR rejects power-supply noise and common-mode interference
- Internal frequency compensation ensures stability without external capacitors
- Wide supply voltage range supports 3V to 32V single-supply or ±1.5V to ±16V dual-supply operation
What is LM392N used for?
The LM392N is widely used in battery-powered sensing circuits, window comparators, and level-detection applications where a low-power op-amp and comparator are both required on the same board. Its low bias current makes it suitable for photodiode amplifiers, thermocouple signal conditioning, and precision voltage monitoring systems. The DIP-8 footprint simplifies prototyping and through-hole assembly in industrial control, automotive, and consumer electronics designs.

Frequently Asked Questions
What is the input bias current of the LM392N?
The LM392N has a typical input bias current (IIB) of 0.25µA at 25°C, with a maximum of 0.4µA. This low bias current makes the device well suited for high-impedance signal sources such as photodiodes, pH electrodes, and bridge sensors where excessive loading would degrade measurement accuracy.
What are the typical applications for the LM392N?
The LM392N is commonly used in window comparators, zero-crossing detectors, battery voltage monitors, temperature-sensing circuits, and low-frequency signal amplifiers. Because it integrates both an operational amplifier and a voltage comparator in a single 8-pin DIP package, it simplifies PCB layout in space-constrained industrial, automotive, and consumer electronic designs.
Is the LM392N RoHS compliant and what package does it use?
The LM392N uses a standard DIP-8 (Dual-In-Line) through-hole package and is marked as non-Pb-free (leaded). If RoHS compliance is required, consider the LM392P or similar Texas Instruments variants rated for lead-free processing. The DIP-8 format is ideal for prototyping and hand-soldering applications.
What is the common-mode rejection ratio (CMRR) of the LM392N?
The LM392N provides a minimum CMRR of 65dB and a nominal value of 70dB. This level of rejection effectively suppresses power-supply ripple and electromagnetic interference on the common-mode input, ensuring reliable operation in noisy industrial and automotive environments.
