com TION KIT EVALUA BLE A IL A V A Audio Subsystem with Mono Class D Speaker and Class H Headphone Amplifiers General Description The MAX97001 mono 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 4 inputs are configurable as 2 differential inputs or 4 single-ended inputs.
The entire subsystem is designed for maximum efficiency.
The high-efficiency, 700mW, 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 groundreferenced 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 signals without compromising the quality of large signals.
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.
