LM4670 Product details

Description

The LM4670 is a fully integrated single-supply high efficiency switching audio amplifier.

Features

an innovative modulator that eliminates the LC output filter used with typical switching amplifiers. Eliminating the output filter reduces external component count, simplifies circuit design, and reduces board area. The LM4670 processes analog inputs with a deltasigma modulation technique that lowers output noise and THD when compared to conventional pulse width modulators. The LM4670 is designed to meet the demands of mobile phones and other portable communication devices. Operating on a single.
