Does it generate noise by touching the operational amplifier?
Does it generate noise by touching the operational amplifier?
Common
- Pressing the IC may have caused stress on the mounting PCB, which may have caused characteristic fluctuations in the external components and affected the frequency characteristics of the IC.
- If there are solder cracks on the mounting PCB, noise characteristics due to abnormal contact of the solder cracks may become apparent when the IC is pressed.
