Maxim Integrated MAX97000

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 differential inputs or four single-ended inputs.

GENERAL DESCRIPTION

FEATURES

S 2.7V to 5.5V Single Supply Voltage S 725mW Speaker Output (VPVDD = 3.7V, ZSPK = 8I + 68µH) S 40mW/Channel Headphone Output (RHP = 16I) S Low-Emission Class D Amplifier S Efficient Class H Headphone Amplifier S Ground-Referenced Headphone Outputs S Two Stereo Single-Ended/Mono Differential Inputs S Integrated Distortion Limiter (Speaker Outputs) S Integrated DPST Analog Switch S No Clicks and Pops S TDMA Noise Free S 2mm x 2mm, 25-Bump 0.4mm Pitch WLP Package MAX97000 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.
