| Market Reality | The TEA2025B is the little stereo amplifier of a generation of speakers, radios, toys and monitors: 2x2.3W at 9V per channel, 16 pins, and a bridge mode for a single louder channel - now NRND at ST and kept alive by a well-behaved clone row (KA2206, CD2025GP, D2025) plus the same-family D-variant. The trap around this part is the Samsung KA2209: an 8-pin flea-power walkman chip whose name sits next to the TEA2025 in substitution tables and whose package, supply range and power class are all different - the kind of "equivalent" that fits nothing. And the quiet engineering detail: the TEA2025B carries internal output-to-ground resistors that tame power-up pops, which most clones reproduce only with external parts added. | The TEA2025B is the little stereo amplifier of a generation of speakers, radios, toys and monitors: 2x2.3W at 9V per channel, 16 pins, and a bridge mode for a single louder channel - now NRND at ST and kept alive by a well-behaved clone row (KA2206, CD2025GP, D2025) plus the same-family D-variant.
