LM4980 High Fidelity Stereo Headphone Audio Amplifier

The LM4980 is a stereo headphone audio amplifier, which when connected to a 3.0V supply, delivers 42mW to a 16Ω load with less than 1% THD+N. With the LM4980 packaged in the SD package, the customer benefits include low profile and small size. This package minimizes PCB area and maximizes output pow.

LM4980 Features

* circuitry that significantly reduces output transients (“clicks” and “pops”) while driving headphones during device turn-on and turn-off without costly external additional circuitry. The LM4980 also includes an externally controlled low-power consumption active-low shutdown mode, and thermal shutdow
