Overview

The LV4904V is a 2-channel class-D amplifier IC that supports digital input. With this single chip and with a minimal number of external components, it is possible to effectively implement class-D amplifiers. The LV4904V incorporates a soft mute function and a gain controller without pop noise, and can be used as a master volume control of the set. Its function settings can be established through an I2C bus interface, but it is also possible to establish these settings simply by pin settings without using the I2C bus. The LV4904V is ideally suited as the power amplifiers in mini components, flat-panel TVs, game machines, electronic musical instruments and other such products.
