EMA1901 Datasheet (Elite Semiconductor) - 1.25W Mono Audio Power Amplifier

EMA1901, 1.25W Mono Audio Power Amplifier

The EMA1901 is an audio power amplifier primarily designed for portable communication applications such as mobile phones and portable multimedia players (PMP).

To an 8Ω BTL load, it can deliver 1.25 watt of continuous average power with less than 1% distortion (THD+N) from a 5VDC supply.

EMA1901 Features

* a low-power consumption shutdown mode, and an internal thermal shutdown protection mechanism. Advanced pop & click circuitry is built in to eliminate noises that would otherwise occur during turn-on and turn-off transitions. The EMA1901 is unity-gain stable and can be configured by external gain-set
