MAX97003
High-Efficiency, Low-Noise Audio Subsystem
Maxim Integrated Products 1
General Description
The MAX97003 audio subsystem combines a mono
speaker amplifier with a stereo headphone amplifier. The
headphone and speaker amplifiers have independent
volume and on/off controls. The four inputs are configu-
rable as two differential or four single-ended inputs.
To minimize output noise, both the headphone and
speaker outputs utilize a downward expander/noise gate
to attenuate noise when no desired input signal is present.
The speaker output incorporates an adjustable dynamic
range compressor (DRC) and distortion limiter to protect
the speaker and maximize loudness. This allows high
gain for low-level signals without compromising the qual-
ity of large signals.
All controls are performed using the two-wire I2C inter-
face. The IC operates in the extended -40NC to +85NC
temperature range, and is available in the 2.0mm x
2.4mm, 20-bump WLP package (0.4mm pitch).
