The MAX4410 stereo headphone driver is designed for portable equipment where board space is at a premium. The MAX4410 uses a unique, patented, 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 16Ω load and has low 0.003% THD + N. A high powersupply rejection ratio (90dB at 1kHz) allows this device to operate from noisy digital supplies without an additional linear regulator. The MAX4410 includes ±8kV ESD protection on the headphone outputs. Comprehensive clickand- 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.
