EMA2011 Datasheet 2.7w Mono Filter-less Class-d Audio Amplifier

Manufacturer: ESMT (Elite Semiconductor Microelectronics Technology)

Overview: ESMT/EMP.

General Description

The EMA2011 is a mono, filter-less class-D audio amplifier.

Operating with 5.0V loudspeaker driver supply, it can deliver 2.7W output power into 4 Ω loudspeaker within 10% THD+N or 2.2W at 1% THD+N.

The EMA2011 is a mono audio amplifier with high efficiency and suitable for the notebook puter, and portable multimedia device.
