With a 4 ohms speaker TBA810 audio amplifier circuit needs to be powered from a power supply with output voltage of 16 V and if we using a 2 ohms load impedance the TBA810 circuit is require a 14.4 volts dc power supply .
This IC is class B amplifier with high efficiency and very low harmonic distortion .
The input voltage range accepted by this power amplifier circuit project is from 4 volts to 20 volts . Main features of this TBA monolithic power amplifier circuit diagram project are : low noise , few external components required , polarity inversion protection , high supply voltage rejection ( 40dB min.) .
This monolithic audio amplifier can be used in many audio applications for car radios ,other audio devices or portable applications .
