dual BTL 14 watt audio amplifier circuit Datasheet for AN7176: Download

Here i share power amplifier based on IC TDA7236 . This amplifier require minimum voltage 0,9 volt and maximum voltage is 1, 6 volt , its very low voltage amplifier. You can use this amplifier everywhere just with one battery 1,5 volt. Power output 16 mW with 32 ohms impedance. see circut below :

In this amplifier circuit using IC TDA8944J as the main amplifier with dual-channel audio amplifier with 2 x 7W output power at 8 Ω impedance. And a minimum supply voltage of 9-18 Volts. In this ic contains two Bridge Tied Load or BTL amplifier. The circuit is often found in audio amplifier in a series of television, besides TDA2003, TDA2006 and so forth. PCB for a series of amplifiers using IC TDA8944J is very compatible with all other types of IC in IC TDA894X family unit , and below is a schematics.
