General Description
The MAX9727 quad audio line driver with 3V
RMS
output is
ideal for portable audio devices where board space and
cost is at a premium. The device uses Maxim’s
DirectDrive
TM
architecture that produces a ground-refer-
enced output from a single supply, eliminating the need
for large DC-blocking capacitors, saving cost, board
space, and component height. A high 100dB PSRR and
low 0.0005% THD+N ensures clean, low-distortion ampli-
fication of the audio signal. Each MAX9727 amplifier can
provide 3V
RMS
to a 1k
load with less than 0.003%
THD+N while operating from a single +5V supply. Each
MAX9727 amplifier can provide 2V
RMS
to a 1k
load with
less than 0.003% THD+N while operating from a single
+3.3V supply.
A shutdown input disables the amplifiers and reduces
quiescent current consumption to less than 100nA. The
MAX9727 features Maxim’s comprehensive click-and-
pop suppression circuitry that reduces audible clicks and
pops during startup and shutdown.
The MAX9727 operates from a single 2.7V to 5.5V sup-
ply, consumes only 3mA of supply current per channel
and is specified over the -40°C to +85°C extended tem-
perature range.
