LM3856 audio amplifier

Overview

1. Function description:
This design is an audio amplifier based on the LM3856 operational amplifier;
it is equipped with an independent button to increase or decrease the volume when the self-locking switch is pressed;
2. Design features:
PCB board size is about 10cm × 10 ㎝, can be sampled at Jialichuang;
except for integrated chips and buttons, other components are basically all SMD components to save PCB space;
it uses microUSB-B for power supply.

The LIS25BA MEMS digital output motion sensor is a low noise, high bandwidth, three-axis digital accelerometer. The LIS25BA has a dedicated TDM interface with a full scale of ±3.85g and a time divisio
How to use IDLE of C5509A
In the C5509A project, when the DSP receives the SLEEP command from the MCU via I2C, it needs to enter the sleep state. Once in the sleep state, the DSP stops at the IDLE statement and no longer runs,
TLC2543 cannot sample data?
I would like to ask everyone, there is no problem with the circuit I connected, and the reference voltage and other aspects are normal, but there is no data output. It becomes zero as soon as the powe
