General Description
The MAX9768 mono 10W Class D speaker amplifier
provides high-quality, efficient audio power with an inte-
grated volume control function.
The MAX9768 features a 64-step dual-mode (analog or
digitally programmable) volume control and mute func-
tion. The audio amplifier operates from a 4.5V to 14V
single supply and can deliver up to 10W into an 8
Ω
speaker with a 14V supply.
A selectable spread-spectrum mode reduces EMI-radiat-
ed 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 tem-
perature range.
