Integrated Silicon Solution
GENERAL DESCRIPTION
The IS31AP2010F is a high efficiency, 2.8W@5.0V mono filter-less Class-D audio power amplifier. A low noise, filter-less PWM architecture eliminates the output filter, reduces external component count, system cost, and simplifying design.
Operating in a single 5.0V supply, IS31AP2010F is capable of driving 4Ω speaker load at a continuous average output of 2.8W@10% THD+N. The IS31AP2010F has high efficiency with speaker load compared to a typical Class- AB amplifier.
