3W STEREO AUDIO AMPLIFIER USING TDA7266D

Little stereo sound intensifier board has been outlined around SMD TDA7266D IC from ST. The TDA7266D is a dual scaffold speaker uncommonly intended for Convenient Sound, LCD television/Screen, PC Motherboard, and video applications. This circuit gives a fantastic sound yield of 3W approx. On every channel with standard sound sign information. The circuit works with 3.5V to 5V. Because of low supply entering this intensifier is appropriate for little size sound devices and convenient audio applications like MP3 player, Voice informing framework, Cautioning signals, Annunciator and so forth.

Particulars

Supply voltage range 3.5 to 5v (most extreme supply 5v because of little pub and small warm zone)

Yield power 3+3w @thd = 10%, rl = 8ω, vcc = 3.7v (3w approx.)

Single supply
