Working Principles

The MAX9717DEBL+T is a class D audio amplifier that utilizes pulse-width modulation (PWM) to amplify audio signals. It operates by rapidly switching the input signal on and off, creating a series of pulses that represent the original audio waveform. These pulses are then filtered and amplified to drive the connected speaker.

Detailed Application Field Plans

The MAX9717DEBL+T is suitable for various audio amplification applications, including but not limited to: - Portable speakers - Headphone amplifiers - Automotive audio systems - Home theater systems - Multimedia devices
