HT4863 - 2.2W stereo headphone power amplifier

General Description

The HT4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω load or 2.5W to a 3Ω load with less than 1.0% THD+N.

In addition, the headphone input pin allows the amplifiers to operate in single-ended mode to drive stereo headphones.
