LM4834 Datasheet 1.75w Audio Power Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4834 1.75W Audio Power Amplifier with DC Volume Control and Microphone Preamp November 1997 LM4834 1.

General Description

The LM4834 is a monolithic integrated circuit that provides DC volume control, and a bridged audio power amplifier capable of producing 1.75W into 4Ω with less than 1.0% (THD).

In addition, the headphone/lineout amplifier is capable of driving 70 mW into 32Ω with less than 0.1%(THD).

The LM4834 incorporates a volume control and an input microphone preamp stage capable of driving a 1 kΩ load impedance.

Key Features

  • an externally controlled, low-power consumption shutdown mode, and both a power amplifier and headphone mute for maximum system flexibility and performance.
