Frequently Asked Questions
What is the input bias current of the LM392M?
The LM392M has a maximum input bias current (IIB) of 0.25µA at 25°C and 0.4µA over the full temperature range. This ultra-low bias current minimizes the loading effect on high-impedance signal sources, making it ideal for precision sensor and instrumentation applications.
What package is the LM392M available in?
The LM392M is available in a Small Outline (SOIC) surface-mount package, which provides a compact footprint suitable for high-density PCB layouts. This package offers excellent thermal performance and is compatible with standard SMT assembly processes used in consumer, industrial, and automotive electronics.
What are typical applications for the LM392M?
The LM392M is commonly used in battery-powered portable devices, industrial sensor signal conditioning, active filter circuits, voltage threshold detection, audio preamplifiers, and automotive sensor interfaces. Its low power consumption and high CMRR of 70dB make it especially well suited for noise-sensitive analog front-end designs.
What is the common-mode rejection ratio (CMRR) of the LM392M?
The LM392M offers a minimum CMRR of 65dB and a typical value of 70dB. This high common-mode rejection ensures that differential signals are amplified accurately while common-mode noise from power supply fluctuations or electromagnetic interference is effectively suppressed.
