This IC was commonly used as the audio amp in many CBs.

The Ta7222 can power a 2ohm load safely, but don’t use more than 14 volts supply. You can use up to 18V with a 4 ohm or higher load. A 2 ohm load would need 1500mF or more output cap (C6) to deliver full bass. A 2 ohm load would also require 1.5 amps from your power supply per amp IC.

If the out put voltage from the amplifier is say V then the power output is V² / Z (speaker impedance). If the impedance decreases the current through the load increases, hence the output stage of the amplifier must be capable of this requirement if not the output component may get burnt. If the impedance increased the out put power will get reduced but no damage to the equipment. Use only the range of recommended speakers only by the manufacturer/ designer

You can use an 8 ohm speaker, but the output power will be reduced by around half.

Sir i have to ask that can we use a Speaker of 8 ohm rather than 4 ohm???
and secondly is there any effect on the circuit by using a low or high ohm’s speaker at the output??

Kindly let me know..
Thanks
