Overview
ESMT/EMP 1W Mono Audio Power Amplifier General Description The EMA1001 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 watt of continuous average power with less than 1% distortion (THD+N) from a 5VDC supply.
EMA1001 Key Specifications „ „ „ „ PSRR at 217Hz, VDD = 5V (Fig.

) Power Output at 2.
6V & 1% THD 250mW(typ.
) Shutdown Current 0.
1µA(typ.
) Features „ Available in space-saving MSOP package Ultra low current shutdown mode BTL output driving capacitive loads Improved pop & click circuitry eliminating noises during turn-on and turn-off transitions „ „ 2.
2 - 5.
5V operation No output coupling capacitors, snubber networks or bootstrap capacitors required „ „ „ The EMA1001 is pin-compatible to National Semi’s LM4890 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.
The EMA1001 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 EMA1001 is unity-gain stable and can be configured by external gain-setting resistors.
„ „ „ Thermal shutdown protection Unity-gain stable External gain configuration capability Applications „ „ „ Mobile Phones PDAs and PMPs Portable Electronic Devices EMP products are Pb-free and RoHS compliant.
