MAX98307 Datasheet 3.3w Mono Class Dg Multilevel Audio Amplifier

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX98307/MAX98308 EVALUATION KIT AVAILABLE 3.3W Mono Class DG Multilevel Audio Amplifier.

General Description

The MAX98307/MAX98308 fully differential mono Class DG multilevel power amplifiers with integrated inverting charge pumps offer highly efficient, high-power audio solutions for portable applications.

Class DG multilevel modulation extends the dynamic range of the output signal by employing a charge-pumpgenerated negative rail as needed to extend the supply range.

This scheme results in high efficiency over a wide output power range.

Key Features

  • eliminate the need for output filtering as compared to traditional Class D devices, reducing component count and cost. The MAX98307’s 16-pin TQFN package features an adjustable gain set by external resistors. The MAX98308’s space-saving 12-bump WLP package features an internally fixed gain of 8.5dB, 11.5dB, 14.5dB, 17.5dB, and 20.5dB set by a single gain input. Both devices operate over the extended -40°C to +85°C temperature range.
