... Detailed Description The NCP2890 audio amplifier can operate under 2.6 V until 5.5 V power supply. It delivers 320 mW rms output power to 4.0 W load (V = 2.6 V) and 1.0 W rms output p power to 8.0 W load (V = 5.0 V). p The structure of the NCP2890 is basically composed of two identical internal power amplifiers; the first one is externally configurable with gain− ...
