Here's the amp circuit diagram: Wuxi Ark Technology Electronic Co.,Ltd. , https://www.arkledcn.com
I've been working on this project for a while now and thought it would be helpful to share some of the diagrams I’ve come across. The ESD diode in use here is the DFN1006 TP-RCLAMP3321P, which has a low capacitance making it ideal for protecting sensitive circuits. The amp circuit diagrams below should give you a good idea of how everything is connected. If you have any questions or need further clarification, feel free to reach out!
