General Description
The MAX4411 fixed-gain, stereo headphone amplifier is
designed for portable equipment where board space is
at a premium. The MAX4411 uses a unique DirectDrive
architecture to produce a ground-referenced output
from a single supply, eliminating the need for large DC-
blocking capacitors, saving cost, board space, and
component height. Additionally, the gain of the
amplifier is set internally (-1.5V/V, MAX4411 and
-2V/V, MAX4411B), further reducing component count.
The MAX4411 delivers up to 80mW per channel into a
16
Ω load and has low 0.003% THD+N. An 86dB at
217Hz power-supply rejection ratio (PSRR) allows this
device to operate from noisy digital supplies without an
additional linear regulator. The MAX4411 includes
±8kV
ESD protection on the headphone outputs. Com-
prehensive click-and-pop circuitry suppresses audible
clicks and pops on startup and shutdown. Independent
left/right, low-power shutdown controls make it possible
to optimize power savings in mixed-mode, mono/stereo
applications.
The MAX4411 operates from a single 1.8V to 3.6V supply,
consumes only 5mA of supply current, has short-circuit
and thermal-overload protection, and is specified over the
extended -40°C to +85°C temperature range. The
MAX4411 is available in a tiny (2mm 2mm 0.6mm),
16-bump chip-scale package (UCSP) and a 20-pin thin
QFN package (4mm 4mm 0.8mm).
