I am using an Audio Module. The schematics of the module can be found below. The module uses a audio amplifier (
TS4990IST) and STM32F0 MCU.
I found out when powering up the module, the module start heating up. In my module, capacitor
C10 is not soldered. Can someone help me to rectify the issue?
I have been reading the datasheet of TS4990 and found out it may require
Cin capacitor at the input (Page 4). Find the screenshot of page 4 below:
Looks like the manufacturer of these modules has forget to add the
Cin Capacitor and may be that's why the module is amplifying DC voltage and hence heating up the module. Am I right?
