  • Product Details

    The MAX9701 evaluation kit (EV kit) is a fully assembled and tested circuit board that uses the MAX9701 filterless Class D amplifier to drive a stereo bridge-tied-load (BTL) speaker in portable audio applications. Designed to operate from a 2.5V to 5.5V DC power supply, the EV kit is capable of delivering 1W per channel into an 8Ω load.

    The EV kit accepts differential or single-ended input signals and provides an option to select between different switching frequency modes of operation.
