1V, Low-Power, DirectDrive, Stereo Headphone  
Amplifier with Shutdown  
MAX9725  
General Description  
Features  
♦ Low Quiescent Current  
2.1mA (MAX9725A–MAX9725D)  
2.3mA (MAX9725E)  
The MAX9725A–MAX9725D fixed-gain, stereo head-  
phone amplifiers are ideal for portable equipment where  
board space is at a premium. The MAX9725E offers the  
flexibility to adjust the gain with external input and feed-  
back resistors. The MAX9725A–MAX9725E use a unique  
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. Fixed gains of -2V/V (MAX9725A),  
-1.5V/V (MAX9725B), -1V/V (MAX9725C), and -4V/V  
(MAX9725D) further reduce external component count.  
The adjustable gain of the MAX9725E DirectDrive head-  
phone amplifier allows for any gain down to -1V/V using  
external resistors.  
♦ Single-Cell, 0.9V to 1.8V Single-Supply Operation  
♦ Fixed Gain Eliminates External Feedback Network  
MAX9725A: -2V/V  
MAX9725B: -1.5V/V  
MAX9725C: -1V/V  
MAX9725D: -4V/V  
♦ Adjustable Gain with External Input and Feedback  
Resistors  
MAX9725E: Minimum Stable Gain of -1V/V  
♦ Ground-Referenced Outputs Eliminate DC Bias  
♦ No Degradation of Low-Frequency Response Due  
to Output Capacitors  
♦ 20mW per Channel into 32Ω  
♦ Low 0.006% THD+N  
♦ High PSRR (80dB at 1kHz)  
♦ Integrated Click-and-Pop Suppression  
♦ Low-Power Shutdown Control  
♦ Short-Circuit Protection  
The MAX9725 delivers up to 20mW per channel into a  
32Ω load and achieves 0.006% THD+N. An 80dB at 1kHz  
power-supply rejection ratio (PSRR) allows the MAX9725  
to operate from noisy digital supplies without an additional  
linear regulator. The MAX9725 includes 8kV ESD protec-  
tion on the headphone output. Comprehensive click-and-  
pop circuitry suppresses audible clicks and pops at  
startup and shutdown. A low-power shutdown mode  
reduces supply current to 0.6µA (typ).  
The MAX9725 operates from a single 0.9V to 1.8V supply,  
allowing the device to be powered directly from a single  
AA or AAA battery. The MAX9725 consumes only  
2.1mA of supply current, provides short-circuit protection,  
and is specified over the extended -40°C to +85°C tem-  
perature range. The MAX9725 is available in a tiny  
(1.54mm x 2.02mm x 0.6mm) 12-bump chip-scale  
package (UCSP™) and a 12-pin thin QFN package  
(4mm x 4mm x 0.8mm).
