MAX97200 - Class H DirectDrive Headphone Amplifier

General Description

The MAX97200 is a 45mW Class H headphone amplifier that runs from a single low 1.8V supply voltage and employs Maxim’s second-generation DirectDrive technology.

Key Features

  • a Dual ModeK internal charge pump to generate the power rails for the amplifier. The charge-pump output can be QPVIN/2 or QPVIN depending on the amplitude of the output signal. When the output voltage is low, the power-supply voltage is QPVIN/2. When the output signal demands larger output voltage, the charge pump switches modes so that a greater power-supply voltage is realized and more output power can be delivered to the load. Second-generation DirectDrive technology improves power consumptio.
