MAX4410EUD
80MW, DirectDrive stereo headphone driver with disconnection
description
The MAX4410 stereo headphone driver is designed for portable devices where board space is premium. The unique MAX4410's DirectDrive architecture generates a single-supply-powered ground-referenced output, eliminating the need for large DC-blocking capacitors, saving cost, board space, and component height.
The MAX4410 provides up to 80MW of channels per 16Ω load and features a low THD+N of 0.003%. The high power supply rejection ratio (90 dB at 1kHz) allows the device to operate on noisy digital supplies without the need for an additional linear regulator. The MAX4410 includes a headphone output with ±8kV ESD protection. Full and popular circuit suppression vocalizations click start and close pop-ups. Independent left/right, low-power shutdown control makes it possible to optimize power savings for mono/stereo applications in mixed mode.
The MAX4410 operates from a single 1.8V to 3.6V supply, consumes only 7 milliamps of supply current, is short-circuit and thermal-overload protected, and is specified over the extended -40°C to +85°C temperature range. The MAX4410 is a tiny (2mm x 2mm x 0.6mm), 16-bump wafer-level package (UCSP™) and 14-pin TSSOP package.
