Audio Subsystem with Mono Class D Speaker  
and Class H Headphone Amplifiers  
General Description  
Features  
Sꢀ2.7V_to_5.5V_Speaker_Supply_Voltage  
The MAX97001 mono audio subsystem combines a  
mono speaker amplifier with a stereo headphone ampli-  
fier and an analog DPST switch. The headphone and  
speaker amplifiers have independent volume control and  
on/off control. The 4 inputs are configurable as 2 differ-  
ential inputs or 4 single-ended inputs.

SꢀNo_Clicks_and_Pops  
The entire subsystem is designed for maximum effi-  
ciency. The high-efficiency, 700mW, Class D speaker  
amplifier operates directly from the battery and con-  
sumes no more than 1FA in shutdown mode. The Class  
H headphone amplifier utilizes a dual-mode charge  
pump to maximize efficiency while outputting a ground-  
referenced signal that does not require output coupling  
capacitors.  
The speaker amplifier incorporates a distortion limiter to  
automatically reduce the volume level when excessive  
clipping occurs. This allows high gain for low-level sig-  
nals without compromising the quality of large signals.

Package  
All control is performed using the 2-wire I2C interface.  
The MAX97001 operates over the extended -40NC to  
+85NC temperature range, and is available in the 2mm x  
2.5mm, 20-bump, WLP package (0.5mm pitch).
