General Description
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.
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 EMA1901 is unity-gain stable and can be configured by external gain-setting resistors. EMP products are RoHS and Halogen free compliant.
- PSRR at 217Hz, VDD = 5V (Fig. 1) Power Output at 5.0V & 1% THD Power Output at 2.6V & 1% THD S.
