Frequently Asked Questions
What is the common-mode rejection ratio of the LM324NE4?
The LM324NE4 has a typical common-mode rejection ratio of 80 dB and a minimum of 65 dB, making it suitable for applications where noise rejection is critical, such as industrial sensor interfaces and precision measurement circuits operating across a wide input voltage range.
How does the LM324NE4 perform in low-power battery applications at 3.3 V?
The LM324NE4 operates from a single supply voltage down to approximately 3 V and draws low quiescent current, making it effective for battery-powered designs. Its 0.25 µA bias current at 25°C and 0.15 µA input offset current minimize loading on high-impedance sources in portable instruments.
When is the LM324NE4 a better fit than a single-channel op-amp in PCB designs?
The LM324NE4 integrates 4 independent op-amp channels in a single DIP-14 package, reducing component count and board space compared to using four discrete single-channel amplifiers. Each channel can be independently configured, supporting multi-stage filter chains or 4-channel signal conditioning within a compact footprint.
