ESMT/EMP EMA1001 1W Mono Audio Power Amplifier General Description Key Specifications The EMA1001 is an audio power amplifier primarily PSRR at 217Hz, VDD = 5V (Fig. 1) 60dB(typ.) designed for portable communication applications Power Output at 5.0V 1% THD 1W(typ.) such as mobile phones and portable multimedia Power Output at 2.6V 1% THD 250mW(typ.) players (PMP). To an 8Ω BTL load, it can deliver 1 watt of Shutdown Current 0.1µA(typ.) continuous average power with less than 1% distortion (THD+N) from a 5VDC supply. Features Available in space-saving MSOP package The EMA1001 is pin-compatible to National Semi’s Ultra low current shutdown mode LM4890 with a superior (THD+N). It does not require BTL output driving capacitive loads output coupling capacitors or bootstrap capacitors, Improved pop click circuitry eliminating noises and is ideal for mobile phone and other low voltage during turn-on and turn-off transitions applications where minimal power consumption is a 2.2 - 5.5V operation primary requirement. No output coupling capacitors, snubber networks or bootstrap capacitors required The EMA1001 features a low-power consumption Thermal shutdown protection shutdown mode, and an internal thermal shutdown Unity-gain stable protection mechanism.
