4411E - MAXIM - QFN-20 -MAX4411ETP

80mW, Fixed-Gain, DirectDrive, Stereo Headphone Amplifier with Shutdown

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, 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. 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 16Ω 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. 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 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).
