Product details

Description

The LM4682 is a fully integrated single supply, high efficiency audio power amplifier solution.

The LM4682 utilizes a proprietary balanced pulse-width modulation technique that lowers output noise and THD and improves PSRR when compared to conventional pulse width modulators.

Features

a stereo headphone amplifier that delivers 60mW into a 32Ω headset with less than 0.5% THD. The LM4682’s DC volume control has a +30dB to.
48dB range when speakers are driven and a range of +13dB to.
65dB when headphones are connected. All amplifiers are protected by thermal shutdown. Additionally, all amplifiers incorporate output current limiting function to protect their outputs from short circuit. The LM4682 features a low-power consumption shutdown mode. And its efficiency r.
