AVAILA Quad Audio Line Driver with 3VRMS Output
The MAX9727 quad audio line driver with 3VRMS output is
ideal for portable audio devices where board space and
cost is at a premium. The device uses Maxim’s
DirectDriveTM architecture that produces a ground-referenced output from a single supply, eliminating the need
for large DC-blocking capacitors and saving cost, board
space, and component height. A high 100dB PSRR and
low 0.0005% THD+N ensures clean, low-distortion amplification of the audio signal. Each MAX9727 amplifier can
provide 3VRMS to a 1kΩ load with less than 0.003%
THD+N while operating from a single +5V supply. Each
MAX9727 amplifier can provide 2VRMS to a 1kΩ 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-andpop suppression circuitry that reduces audible clicks and
pops during startup and shutdown. …
