LM4902 Boomer™ Audio Power Amplifier Series 265mWat 3.3V Supply Audio Power
Amplifier with Shutdown Mode
Checkfor Samples: LM4902
1FEATURES DESCRIPTIONThe LM4902isa bridged audio power amplifier
23• VSSOP and WSON Packaging capableof delivering 265mWof continuous average
• No Output Coupling Capacitors, Bootstrap power into an 8Ω load with 1% THD+N froma 3.3V
Capacitors,or Snubber Circuits are Necessary power supply.
Thermal Shutdown Protection Circuitry Boomer™ audio power amplifiers were designed
• Unity-Gain Stable specificallyto provide high quality output power from low supply voltage while requiringa minimal
• External Gain Configuration Capabilityamountof external components. Since the LM4902
• Latest Generation "Click and Pop" does not require output coupling capacitors, bootstrap
Suppression Circuitry capacitorsor snubber networks,itis optimally suited
for low-power portable applications.
APPLICATIONSThe LM4902 features an externally controlled, low
• Cellular Phones power consumption shutdown mode, and thermal
PDA's shutdown protection.
Any Portable Audio Application The closed loop response of the unity-gain stable
LM4902 can be configured by external gain-setting
KEY SPECIFICATIONS resistors.
