- 80 dB typical common-mode rejection ratio enabling accurate signal amplification in noisy environments
- Internal frequency compensation eliminating the need for external capacitors and simplifying PCB layout
Applications
The LM2902KNE4 serves signal conditioning, comparator, and active filter circuits in industrial instrumentation and consumer electronics where four independent amplifier stages are needed in one package. Its wide supply voltage range from 3 V to 26 V makes it compatible with both low-power microcontroller systems and higher-voltage analog front-ends. Typical uses include transducer amplification, summing amplifiers in audio mixers, and low-frequency filter stages in sensor processing boards.

Frequently Asked Questions
What supply voltage range does the LM2902KNE4 support, and can it run from a single supply?
The LM2902KNE4 operates from a single supply of 3 V to 26 V or a dual supply of ±1.5 V to ±13 V, giving designers flexibility to power it directly from standard 5 V, 12 V, or 15 V rails without a split supply, which simplifies system power architecture.
How does the 80 dB CMRR of the LM2902KNE4 benefit differential signal applications?
An 80 dB typical common-mode rejection ratio means the device suppresses common-mode interference by a factor of 10,000, keeping amplified output free from power-line noise and ground-loop errors. This is essential in bridge sensor amplifiers and instrumentation front-ends where measurement accuracy depends on rejecting common-mode voltages of several volts.
For a compact analog design, how does packaging four op-amps in the LM2902KNE4 DIP-14 compare to using discrete single-channel parts?
Using the LM2902KNE4 replaces four individual op-amp ICs with a single 14-pin DIP package, reducing board area by up to 75% and cutting component count significantly. The 2.54 mm pin pitch makes it compatible with standard IC sockets, and consolidating 4 channels into one part also reduces procurement SKU count and bill-of-materials cost.
