The MAX4368EKA from Maxim Integrated is a Class AB audio power amplifier with a shutdown feature, delivering 330 mW into a 16 Ω load from a single mono channel. It runs on a 2.3 V to 5.5 V supply.
330 mW into 16 Ω — what that means on the bench
330 mW into a 16 Ω speaker is enough for line-level audio or a small earpiece driver.
