1. AD8138 can be used to achieve
The single-ended to differential conversion circuit uses AD8138 from AD. This amplifier has a wide analog bandwidth (320MHz, -3dB, gain 1) and can realize the function
This is a typical "three-no" Bluetooth speaker with a unique shape. It supports Bluetooth, FM, audio input, and TF. It has multiple functions and a loud volume.The knockoff speaker is naturally not co
The following is the circuit diagram of my main control chip. I originally thought that the low-speed crystal oscillator would not be used, so I deleted the low-speed crystal oscillator and only kept
