ADIMAX97220AEVKIT+
Overview
The MAX97220AEVKIT+ is an evaluation board designed to demonstrate the capabilities of the MAX97220A, a differential input DirectDrive stereo headphone amplifier. It provides a platform to test the IC's ability to drive 125mW into 32-ohm loads or provide a 3VRMS output into 600-ohm loads from a single 2.5V to 5.5V supply. The board eliminates the need for bulky DC-blocking capacitors at the output, saving space and improving low-frequency response.
Why Choose This Part
The DirectDrive architecture generates a ground-referenced output from a single supply, which removes the need for large output-coupling capacitors and prevents low-frequency roll-off. It features fully differential inputs for excellent noise rejection and allows for externally adjustable gain to match specific system requirements.
Applications
Key Specifications
Getting Started
Connect a 2.5V to 5.5V DC power supply to the VDD and GND pads. Apply a differential or single-ended audio signal to the input headers and connect headphones or a load to the 3.5mm stereo jack. Use the onboard jumpers to toggle the shutdown pin and evaluate power-saving features.
