MAX9768ETG+T

MAX9768ETG+T is a 10W mono class D speaker amplifier with volume control. It provides high-quality, efficient audio power with an integrated volume control function. It features a 64-step dual-mode (analogue or digitally programmable) volume control and mute function. The audio amplifier operates from a 4.5V to 14V single supply and can deliver up to 10W into an 8ohm speaker with a 14V supply. A selectable spread-spectrum mode reduces EMIradiated emissions, allowing the device to pass EMC testing with ferrite bead filters and cable lengths up to 1m. The MAX9768 can be synchronized to an external clock, allowing synchronization of multiple Class D amplifiers. Applications include notebook computers, flat-panel displays, multimedia monitors, GPS navigation systems, and security/personal mobile radio.
