LM4820-6 Datasheet Fixed Gain 1watt Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4820-6 Fixed Gain 1 Watt Audio Power Amplifier April 2002 LM4820-6 Fixed Gain 1 Watt Audio Power.

General Description

The LM4820-6 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable munication device applications.

It is capable of delivering 1 watt of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) at 6dB of BTL gain from a 5VDC power supply.

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external ponents.

Key Features

  • a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the LM4820-6 features an internal thermal shutdown protection mechanism. The LM4820-6 contains advanced pop & click circuitry which eliminates noises which would otherwise occur during turn-on and turn-off transitions.
