Audio Subsystem with Mono Class D
Speaker and Class H Headphone Amplifiers MAX97002
19-5111; Rev 1; 7/10
Simplified Block Diagram
General Description
The MAX97002 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.
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.
All control is performed using the 2-wire I2C interface.
The MAX97002 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).
