General Description
The LM4902 is a bridged audio power amplifier capable of delivering 265mW of continuous average power into an 8Ω load with 1% THD+N from a 3.3V power supply.
Key Features
- an externally controlled, low power consumption shutdown mode, and thermal shutdown protection. The closed loop response of the unity-gain stable LM4902 can be configured by external gain-setting resistors. j THD+N at 1kHz for 675mW continuous average output power into 8Ω, VDD = 5V j Shutdown current 1.0% (max) 0.1µA (typ) Features n MSOP and LLP packaging n No output coupling capacitors, bootstrap capacitors, or snubber circuits are necessary n Thermal shutdown protection circuitry n Unity-g.
