LM4861 Datasheet 1.1w Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4861 1.1W Audio Power Amplifier with Shutdown Mode May 1997 LM4861 1.

General Description

The LM4861 is a bridge-connected audio power amplifier capable of delivering 1.1W of continuous average power to an 8Ω load with 1% (THD) using a 5V power supply.

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging.

Since the LM4861 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optimally suited for low-power portable systems.

Key Features

  • an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4861 can be configured by external gain-setting resistors. Key Specifications n THD at 1 kHz at 1W continuous average output power into 8Ω n Output power at 10% THD+N at 1 kHz into 8Ω n Shutdown Current 1.0% (max) 1.5W (typ) 0.6 µA (typ) Features n No output coupling capacitors, bootstrap capacitors, or snubber circuits are necessary n Small Outli.
