MAXIM MAX4410 User Manual

General Description
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 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.
Applications
Features
♦ No Bulky DC-Blocking Capacitors Required ♦ Ground-Referenced Outputs Eliminate DC-Bias
Voltages on Headphone Ground Pin
♦ No Degradation of Low-Frequency Response Due
to Output Capacitors
♦ 80mW Per Channel into 16Ω
♦ Low 0.003% THD + N ♦ High PSRR (90dB at 1kHz) ♦ Integrated Click-and-Pop Suppression ♦ 1.8V to 3.6V Single-Supply Operation ♦ Low Quiescent Current ♦ Independent Left/Right, Low-Power
Shutdown Controls
♦ Short-Circuit and Thermal Overload Protection ♦ ±8kV ESD-Protected Amplifier Outputs
♦ Available in Space-Saving Packages

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device
can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder profiles recom­mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and convection reflow. Preheating is required. Hand or wave soldering is not allowed.
