General Description
The MAX4410 stereo headphone driver is designed for
portable equipment where board space is at a
premium. The MAX4410 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.
The MAX4410 delivers up to 80mW per channel into a
16
Ω load and has low 0.003% THD + N. A high power-
supply rejection ratio (90dB at 1kHz) allows this device to
operate from noisy digital supplies without an additional
linear regulator. The MAX4410 includes
±8kV ESD pro-
tection on the headphone outputs. Comprehensive 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 MAX4410 operates from a single 1.8V to 3.6V supply,
consumes only 7mA of supply current, has short-circuit
and thermal overload protection, and is specified over the
extended -40°C to +85°C temperature range. The
MAX4410 is available in a tiny (2mm x 2mm x 0.6mm),
16-bump chip-scale package (UCSP) and a 14-pin
TSSOP package.
