Mode
Check for Samples: LM4862 FEATURES DESCRIPTION The LM4862 is a bridge-connected audio power
amplifier capable of delivering typically 675mW of
continuous average power to an 8О© load with 1%
THD+N from a 5V power supply. 1 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 Compatible with LM4861 APPLICATIONS Portable Computers
Cellular Phones
Toys and Games KEY SPECIFICATIONS Boomer audio power amplifiers were designed
specifically to provide high quality output power with a
minimal amount of external components. 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. THD+N for 500mW Continuous Average …
