LM4834 Overview
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.
