Elite Micro<strong>Power</strong> Inc.Preliminary EMA10031.2W Fully Differential <strong>Audio</strong> <strong>Power</strong> <strong>Amplifier</strong>with Shutdown SelectGeneral DescriptionThe EMA1003 is a fully differential audio poweramplifier primarily designed for demandingapplications in mobile phones and other portablecommunication device applications. It is capable ofdelivering 1.2 watt of continuous average power toan 8Ω BTL load with less than 1% distortion (THD+N)from a 5VDC power supply.The EMA1003 does not require output couplingKey Specifications.Improved PSRR at 217Hz.<strong>Power</strong> Output at 5.0V, 8Ω& 1% THD.<strong>Power</strong> Output at 2.6V,8Ω& 1% THD.Shutdown currentFeatures. Fully differential amplification. Available packages FBP, MSOP.Ultra low current shutdown mode70dB(typ)1.2W(typ)300mW(typ)0.1µA (typ)capacitors or bootstrap capacitors, and therefore isideally suited for mobile phone and other lowvoltage applications where minimal powerconsumption is a primary requirement..Can drive capacitive loads up to 500 pF.Improved pop & click circuitry eliminates noisesduring turn-on and turn-off transitions.2.2 - 5.5V operation.No output coupling capacitors, snubber networksThe EMA1003 features a low-power consumptionshutdown mode. To facilitate this, shutdown may beenabled by either logic high or low depending onmode selection. Driving the shutdown mode pineither high or low enables the shutdown select pin tobe driven in a likewise manner to enable Shutdown.Additionally, the EMA1003 features an internalthermal shutdown protection mechanism.or bootstrap capacitors required.Unity-gain stable.External gain configuration capability.Shutdown high or low selectivity.High CMRRApplications. Mobile phones. PDAsThe EMA1003 contains advanced pop & click. Portable electronic devicescircuitry which eliminates noises which wouldotherwise occur during turn-on and turn-offtransitions.The EMA1003 is unity-gain stable and can beconfigured by external gain-setting resistors.Elite Micro<strong>Power</strong> Inc. reserves the right to make changes to improve reliability or manufacturability without notice,and customers are advised to obtain the latest version of relevant information prior to placing orders.DSA1003R0 Page 1 of 13 www.elitemicropower.com
