LM4882 Datasheet 250mw Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4882 250mW Audio Power Amplifier with Shutdown Mode January 1998 LM4882 250mW Audio Power Amplifier with Shutdown.

General Description

The LM4882 is a single-ended audio power amplifier capable of delivering 250 mW of continuous average power into 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 components using surface mount packaging.

Since the LM4882 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems.

Key Features

  • an externally controlled, low power consumption shutdown mode which is virtually clickless and popless, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LM4882 can be configured by external gain-setting resistors. Key Specifications n THD + N at 1 kHz at 250 mW continuous average output power into 8Ω n Output Power at 1% THD + N at 1kHz into 4Ω n THD + N at 1 kHz at 85 mW continuous average output power into 32Ω n Shutdown Current 1.0% (max) 380mW (typ) 0.1%.
