LM4902 Datasheet 265mw At 3.3v Supply Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4902 265mW at 3.3V Supply Audio Power Amplifier with Shutdown Mode February 2002 LM4902 265mW at 3.

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.

Boomer ® audio power amplifiers were designed specifically to provide high quality output power from a low supply voltage while requiring a minimal amount of external ponents.

Since the LM4902 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is optimally suited for low-power portable applications.

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.
