3W Mono/Stereo BTL Audio Power Amplifiers
with Shutdown
General Description
The MAX9710/MAX9711 are stereo/mono 3W bridge-tied
load (BTL) audio power amplifiers. These devices are
PC99/01 compliant, operate from a single 4.5V to 5.5V
supply, and feature an industry-leading 100dB PSRR,
which allows these devices to operate from noisy sup-
plies without additional, costly power-supply condition-
ing. An ultra-low 0.005% THD+N ensures clean,
low-distortion amplification of the audio signal while
patented click-and-pop suppression eliminates audible
transients on power and shutdown cycles. Power-saving
features include low 2mV V_OS (minimizing DC current
drain through the speakers), low 7mA supply current,
and a 0.5µA shutdown mode. A MUTE function allows
the outputs to be quickly enabled or disabled.
These devices include thermal overload protection, are
specified over the extended -40°C to +85°C tempera-
ture range, and are supplied in thermally efficient pack-
ages. The MAX9710 is available in either a 20-pin thin
QFN package (5mm ✕ 5mm ✕ 0.8mm) or a 16-pin
TSSOP-EP package. The MAX9711 is available in a 12-
pin thin QFN package (4mm ✕ 4mm ✕ 0.8mm).
