Audio Subsystem with Mono Class D
Speaker and Class H Headphone Amplifier MAX97000
General Description
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.
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.
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 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).
