Low RF Susceptibility, Mono Audio  
Subsystem with DirectDrive Headphone Amplifier  
MAX987  
General Description  
Features  
Low Emissions, Filterless Class D Amplifier  
The MAX9877 combines a high-efficiency Class D  
audio power amplifier with a stereo Class AB capacitor-  
less DirectDrive® headphone amplifier. Maxim’s 3rd  
generation, filterless Class D amplifier with active emis-  
sions limiting technology provides Class AB perfor-  
mance with Class D efficiency.  
Achieves Better than 10dB Margin Under EN55022  
Class B Limits  
Low RF Susceptibility Design Rejects TDMA  
Noise from GSM Radios  
Input Mixer with User-Defined Input Mode  
725mW Speaker Output (R

DD  
The MAX9877 delivers up to 725mW from a 3.7V supply  
into an 8Ω load with 87% efficiency to extend battery life.  
The filterless modulation scheme combined with active  
emissions limiting circuitry and spread-spectrum modu-  
lation greatly reduces EMI while eliminating the need for  
output filtering used in traditional Class D devices.

SPK  
OUT  
The stereo Class AB headphone amplifier in the  
MAX9877 uses Maxim’s patented DirectDrive architec-  
ture, that produces a ground-referenced output from a  
single supply, eliminating the need for large DC-blocking  
capacitors, saving cost, space, and component height.  
1.6Ω Analog Switch for Speaker Amplifier Bypass

High Headphone Amplifier PSRR (84dB at 217Hz)  
I2C Control  
Hardware and Software Shutdown Mode  
Click-and-Pop Suppression  
Current-Limit and Thermal Protection  
Available in a Space-Saving, 2.5mm x 2.0mm WLP  
Package  
The device utilizes a user-defined input architecture,  
three preamplifier gain settings, an input mixer, volume  
control, comprehensive click-and-pop suppression, and  
I2C control. A bypass mode feature disables the integrat-  
ed Class D amplifier and utilizes an internal DPST switch  
to allow an external amplifier to drive the speaker that is  
connected at the outputs of the MAX9877.  
Ordering Information  
The MAX9877 is available in a thermally efficient,  
space-saving 20-bump WLP package.
