Product Details

The MAX4338 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that evaluates the MAX4338 audio amplifier. The MAX4338 EV kit is designed to be driven by the lineout of a CD player or directly connected to any stereo audio source. The MAX4338 EV kit includes RCA jacks on the input and a 3.5mm headphone jack on the output to facilitate easy connections to the circuit board.

This MAX4338 EV kit can also be used to evaluate the MAX4233 high-output-drive, rail-to-rail op amp.
