The MAX9768 mono 10W Class D speaker amplifier provides high-quality, efficient audio power with an integrated volume control function.

The MAX9768 features a 64-step dual-mode (analog 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 8Ω speaker with a 14V supply.

A selectable spread-spectrum mode reduces EMI-radiated 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.

The MAX9768 features high 77dB PSRR, low 0.08% THD+N, and SNR up to 97dB. Robust short-circuit and thermal-overload protection prevent device damage during a fault condition. The MAX9768 is available in a 24-pin thin QFN-EP (4mm x 4mm x 0.8mm) package and is specified over the extended -40°C to +85°C temperature range.

Product Detail

The MAX9768 evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) that demonstrates the capabilities of the MAX9768 mono 10W Class D speaker amplifier with volume control. The MAX9768 EV kit also includes Windows® 98SE/2000/XP-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the MAX9768.

The MAX9768 evaluation system (EV system) consists of the MAX9768 EV kit and a companion CMAXQUSB serial-interface board. The CMAXQUSB interface board allows a PC to control an I²C interface using its USB port. Order the MAX9768 EV system (MAX9768EVCMAXQU+) for a complete PC-based evaluation of the MAX9768. Order the MAX9768 EV kit (MAX9768EVKIT+) if you already have a MAX9768-compatible serial interface.
