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