19-2618; Rev 2; 9/06 EVALUATION KIT AVAILABLE 80mW, Fixed-Gain, DirectDrive, Stereo Headphone Amplifier with Shutdown MAX4411 General Description Features The MAX4411 fixed-gain, stereo headphone amplifier is No Bulky DC-Blocking Capacitors Required designed for portable equipment where board space is Fixed -1.5V/V Gain Eliminates External Feedback at a premium. The MAX4411 uses a unique, patented Network DirectDrive architecture to produce a ground-refer- MAX4411: -1.5V/V enced output from a single supply, eliminating the need MAX4411B: -2V/V for large DC-blocking capacitors, saving cost, board Ground-Referenced Outputs Eliminate DC-Bias space, and component height. Additionally, the gain ofthe amplifier is set internally (-1.5V/V, MAX4411 and Voltages on Headphone Ground Pin -2V/V, MAX4411B), further reducing component count. No Degradation of Low-Frequency Response Due The MAX4411 delivers up to 80mW per channel into a to Output Capacitors 16 load and has low 0.003% THD+N. An 86dB at 80mW per Channel into 16 217Hz power-supply rejection ratio (PSRR) allows this Low 0.003% THD+N device to operate from noisy digital supplies without an High PSRR (86dB at 217Hz) additional linear regulator. The MAX4411 includes ±8kV Integrated Click-and-Pop Suppression ESD protection on the headphone outputs. Com- 1.8V to 3.6V Single-Supply Operation prehensive click-and-pop circuitry suppresses audible clicks and pops on startup and shutdown. Independent Low Quiescent Current (5mA) left/right, low-power shutdown controls make it possible Independent Left/Right, Low-Power to optimize power savings in mixed-mode, mono/stereo Shutdown Controls applications. Short-Circuit and Thermal-Overload Protection The MAX4411 operates from a single 1.8V to 3.6V supply, ±8kV ESD-Protected Amplifier Outputs consumes only 5mA of supply current, has short-circuit Available in Space-Saving Packages and thermal-overload protection, and is specified over the 16-Bump UCSP (2mm 2mm 0.6mm) extended -40°C to +85°C temperature range. The 20-Pin Thin QFN (4mm 4mm 0.8mm) MAX4411 is available in a tiny (2mm 2mm 0.6mm),16-bump chip-scale package (UCSPTM) and a 20-pin thin
