EMA2901 - 2.5W Mono Audio Power Amplifier

General Description

The EMA2901 is an audio power amplifier primarily designed for portable communication applications such as mobile phones and portable multimedia players (PMP).

To a 4Ω BTL load, it can deliver 2.5 watt of continuous average power with typical 10% distortion (THD+N) from a 5VDC supply.

Key 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 EMA2901 is unity-gain stable and can be configured by ext.

mplifier primarily designed for portable communication applications such as mobile phones and portable multimedia players (PMP). To a 4Ω BTL load, it can deliver 2.5 watt of continuous average power with typical 10% distortion (THD+N) from a 5VDC supply. Typical THD+N is about 1% at 1.8Watt. The EMA2901 is pin-compatible to National Semi’s LM4990 Micro-SMD package with a superior (THD+N). It does not require output coupling capacitors or bootstrap capacitors, and is ideal for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.
