• MAX9796EBX+TG45 Application Field and Working Principles

• Linear - Amplifiers - Audio

  • Introduction

    The MAX9796EBX+TG45 device is an audio amplifier that combines a high-voltage, high-current, low-noise, low distortion amplifier with a wide range voltage regulator. The device also incorporates a bridge rectifier, feedback amplifier and a high side current driver. The MAX9796EBX+TG45 is a single-supply (±1.8V to ±10V) amplifier that provides up to 57mA of output current for stereo head-phones applications. It is designed to deliver true stereo sound with high dynamic range and low noise.

  • Application Fields

    The MAX9796EBX+TG45 device can be used in a variety of audio applications including mobile phones, home theater receivers and Portable media players. The device is capable of driving both stereo and mono headphones. It is well suited for applications with wide supply voltage ranges and low noise as well as applications requiring a low power/low current envelope.

  • Working Principle

    The MAX9796EBX+TG45 device works on the principle of applying a DC voltage to an inductor, which creates an electromotive force (EMF). The EMF is used to drive the output transistors and create a high current supply. In addition, the MAX9796EBX+TG45 incorporates a high gain/low noise feedback amplifier. This amplifier senses the output voltage and adjusts the voltage to a predetermined level. As a result, the output voltage remains stable regardless of changes in the input voltage or supply current.
