General Description
The MAX13330/MAX13331 stereo headphone amplifiers
are designed for automotive applications requiring out-
put short-circuit and ESD protection to battery/ground
with diagnostics. These devices use Maxim’s unique
DirectDrive architecture to produce a ground-refer-
enced output from a single supply, eliminating the need
for large DC-blocking capacitors, saving board space
and component height. The gain of the amplifier is set
internally (-1.5V/V) on the MAX13330 or adjusted exter-
nally with resistors on the MAX13331.
The MAX13330/MAX13331 deliver 120mW per channel
into a 16
Ω load or 135mW into a 32Ω load and have a
low 0.01% THD+N. Low output impedance and the effi-
cient integrated charge pump allows the device to drive
loads as low as 8
Ω, enabling the use of small loud-
speakers. An 80dB at 217Hz PSRR allows these
devices to operate from noisy digital supplies without
an additional linear regulator. These devices include
±15kV Human Body Model ESD protection and short-
circuit protection up to +45V at the headphone outputs.
Comprehensive click-and-pop circuitry suppresses
audible clicks and pops on startup and shutdown. A
low-power shutdown mode reduces the supply current
to 3A (typ).
The MAX13330/MAX13331 are specified from -40°C to
+105°C AEC-Q100 Level 2 automotive temperature
range and are available in a 16-pin QSOP package.
