In the fields of medical equipment, automotive instrumentation, and industrial control, when equipment design involves strain gauges, sensor interfaces, and current monitoring, precision analog front-end amplifiers are often required to extract and amplify very weak real signals and suppress common unwanted signals such as mode voltage and noise.First, the designer will concentrate on ensuring tha...

As single-chip systems are more and more widely used in consumer electronics, medical, industrial automation, intelligent instrumentation, aerospace and other fields, single-chip systems are facing increasing threats of electromagnetic interference (EMI). Electromagnetic compatibility (EMC) covers both the emission and sensitivity of the system. If a microcontroller system meets the following thre...

How to judge accurately whether the IC in the circuit is working or not , good or bad, is an important content of repairing TV, audio and video equipment. If the judgment is not accurate, we often have to spend great efforts replacing the new integrated circuit and at the same time the fault still exists, so we should make a correct judgment on the...

OverviewThe LM358 includes two independent, high gain, internal frequency compensation double operational amplifiers,  and it’s suitable for single power supply with a wide range of voltage, and also suitable for dual power operation mode.Under recommended operating conditions, the power supply current is independent of the power supply voltage. Its scope of use includes sensor amplifier...

Principle one:We should understand DC/DC power supply and DC/DC conversion circuit classification.DC/DC power supply circuit is also known as DC/DC conversion circuit. Its main function is to carry out input/output voltage conversion.Generally we call the voltage transformation process of input power supply voltage within 72V DC/DC conversion.Common power supply is mainly divided into vehicle and ...
