Evaluation Kit for the MAX4411

Please check latest availability status for a specific part variant.


The MAX4411 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that evaluates the MAX4411 fixed gain, DirectDrive® stereo headphone amplifier. The DirectDrive architecture of the MAX4411 eliminates the two large DC-blocking capacitors typically required between the output of the amplifier and the headphones. Additionally, the gain of the amplifier is set internally, (-1.5V/V, MAX4411 and -2V/V, MAX4411B) further reducing component count.
