Product Details

The MAX9724A evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) that uses the MAX9724A IC to drive a stereo headphone in portable applications. The MAX9724A is a 60mW stereo headphone amplifier with adjustable gain and DirectDrive® outputs. Maxim's DirectDrive technology eliminates the need for bulky DC-blocking capacitors at the output of the amplifier.

The EV kit is configured for a -1.5V/V gain and is designed to operate from a 2.7V to 5.5V DC power supply. The EV kit is capable of delivering up to 60mW per channel into a 32Ω load and achieving 0.02% THD+N.

The MAX9724A EV kit can also be used to evaluate the MAX9724B fixed-gain amplifier. Contact Maxim for a free sample of the MAX9724B IC.
