Dual TDA72665 BT AMP

## DAY 1 :11th july 2025 Read the Datasheets

Started out by reading the datasheet and figuring out how to get 50watt output in one speaker. Also researched about the power supply that i would need to run this i am likely going to need a Transformer of a SMPS will be adding the Compatibilities of both in the circuit

Time spent-2 hr

*DAY 2 :13th July 2025 Completed the Schematics and Componenet assignment *

made dual speaker output using 2 of 7265 Ic for 50 watt output each also added a split supply to convert 12-0-12 to +12 and -12v.

Time spent-2hr

DAY 3 :16th July 2025 Assigned the Components and PCB

Assigned the components and complted the PCB checked and shortlisted all the Parts i will be requiring. Since this is a audio based circuit so i had to keeep in mind the noise that might be there due to the signal interferenece.

Time spent - 5hrs
