The MAX97002 is an integrated audio subsystem with mono Class D speaker and Class H headphone amplifiers. The speaker amplifier supports 700mW output power and the headphone amplifier supports 2.5V headphone output. It supports low power shutdown mode and uses 2-wire I2C interface for control.
The MAX97002 is a mono audio subsystem that combines a 2.7 V‑5.5 V speaker amplifier with a 1.6 V‑2 V stereo headphone amplifier and an analog DPST switch. Both amplifiers feature independent volume control, a distortion limiter, and a ground‑referenced output design that eliminates the need for coupling capacitors. Control is performed via a 2‑wire I²C interface.
The device operates over an extended temperature range of –40 °C to +85 °C and is offered in a 2 mm × 2.5 mm, 20‑bump WLP package. The datasheet provides detailed electrical characteristics, pin configurations, timing specifications, and layout recommendations for optimal performance in cell phones, portable media players, and other audio applications.
