VCC=9V;RL=8Ω/2W

Bridge Application
VCC=9V;RL=8Ω/5W
VCC=9V;RL=4Ω/8W

Specifications

Supply Voltage min = DC3v @ 500mA
Supply Voltage max = DC12v @ 500mA
Supply Voltage recommended = DC9v @500mA

      It seems that TEA2025 is obsolete, but you can still find it online and on ebay. It seems there is not substitution available.
