Product Details

The MAX9759 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that uses the MAX9759 to drive a mono bridge-tied-load (BTL) speaker in portable audio applications. Designed to operate from a 3.0V to 5.5V DC power supply, the EV kit is capable of delivering 3.2W of continuous power into a 4Ω load.

The MAX9759 EV kit accepts differential or single-ended input signals, provides an option to select between different switching frequency modes of operation, and allows for external clock synchronization of multiple, Maxim Class D amplifiers.
