The LM4870 is a bridge-connected audio power amplifier capable of
delivering 1.1W of continuous average power to an 8[Ohm] load with
less than 0.5% THD+N over the audio spectrum from a 5V power supply.
Boomer audio power amplifiers were designed specifically to provide high
quality output power with a minimal number of external components.
Since the LM4870 does not require output coupling capacitors, bootstrap
capacitors or snubber networks, it is optimally suited for low-power
portable systems.
