Audio Subsystem with Mono Class D  
Speaker and Class H Headphone Amplifier  
General Description  
Features  
Sꢀ1.6V_to_2.0V_Headphone_Supply_Voltage  
The MAX97000 audio subsystem combines a mono  
speaker amplifier with a stereo headphone amplifier and  
an analog DPST switch. The headphone and speaker  
amplifiers have independent volume control and on/off  
control. The four inputs are configurable as two differen-  
tial inputs or four single-ended inputs.

+_68µH)  
Sꢀ40mW/Channel_Headphone_Output_(R _=_16I)  
The entire subsystem is designed for maximum efficiency.  
The high-efficiency 725mW Class D speaker amplifier  
operates directly from the battery and consumes 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.

SꢀTwo_Stereo_Single-Ended/Mono_Differential_Inputs  
SꢀIntegrated_Distortion_Limiter_(Speaker_Outputs)  
SꢀIntegrated_DPST_Analog_Switch  
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.  
SꢀNo_Clicks_and_Pops  
SꢀTDMA_Noise_Free  
All control is performed using the 2-wire, I2C interface.  
The MAX97000 operates in the extended -40NC to +85NC  
temperature range, and is available in the 2mm x 2mm,  
25-bump WLP package (0.4mm pitch).
