FEATURES - 2 No Output Coupling Capacitors, Bootstrap Capacitors or Snubber Circuits are Necessary - Small Outline or PDIP Packaging - Unity-Gain Stable - External Gain Configuration Capability - Pin patible with LM4861 APPLICATIONS - Portable puters - Cellular Phones - Toys and Games KEY SPECIFICATIONS - THD+N for 500m W Continuous Average Output Power at 1k Hz into 8Ω 1% (max) - Output Power at 10% THD+N at 1k Hz into 8Ω 825 m W (typ) - Shutdown Current 0.7μA (typ) DESCRIPTION The LM4862 is a bridge-connected audio power amplifier capable of delivering typically 675m W of continuous average power to an 8Ω load with 1% THD+N from a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external ponents. Since the LM4862 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optimally suited for low-power portable systems. The LM4862 features an externally controlled, lowpower consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4862 can be configured by external gain-setting resistors.
