Product Details

The MAX9700B evaluation kit (EV kit) is a fully assembled and tested circuit board that uses the MAX9700B filterless class D amplifier to drive a mono 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 1.2W into an 8Ω load.

The EV kit accepts differential or single-ended input signals. The EV kit provides an option to select between different switching frequency modes of operation. The MAX9700B EV kit also evaluates the MAX9700A/MAX9700C/MAX9700D and the MAX9712.
