Description: 1.25W Mono Audio Power Amplifier

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

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. Typical THD+N is about 0.015% at 1Watt. The EMA1901 is pin-compatible to National Semi’s LM4890 Micro-SMD pack
