Part Details:

LM4878 October 2002 1 LM4878 Watt 1 Watt Audio Power Amplifier in micro SMD packagewith Shutdown Logic Low Audio General Description Key Specifications The LM4878 is a bridge-connected audio power amplifier j Power Output at 0.2% THD 1 W (typ) Power capable of delivering 1 W of continuous average power to an8 load with less than .2% (THD) from a 5V power supply. j Shutdown Current 0.01 µA (typ) Boomer audio power amplifiers were designed specifically toprovide high quality output power with a minimal amount of Features external components. Since the LM4878 does not require Amplifier n Internal pulldown resistor on shutdown. output coupling capacitors or bootstrap capacitors. It is op-timally suited for low-power portable applications. n micro SMD package (see App. note AN-1112) n 5V - 2V operation The LM4878 features an externally controlled, low-powerconsumption shutdown mode, as well as an internal thermal n No output coupling capacitors or bootstrap capacitors. shutdown protection mechanism. n Unity-gain stable The unity-gain stable LM4878 can be configured by external n External gain configuration capability in gain-setting resistors. Applications micro n Cellular Phones n Portable Computers n Low Voltage Audio Systems SMD Typical Application package with Shutdown Logic Low 10136001 FIGURE 1.
