Product Details

The MAX9718A evaluation kit (EV kit) is a fully assembled and tested circuit board that uses the MAX9718A differential audio amplifier to drive a mono bridge-tied load (BTL) speaker in portable audio applications. Designed to operate from a 2.7VDC to 5.5VDC power supply, the EV kit is capable of delivering 1.1W into an 8Ω load.

The MAX9718A inputs can tolerate a DC offset level of 0.5V through (VCC - 1.2V) from an input source, therefore eliminating the need for input-signal coupling capacitors. The EV kit provides an option to bypass the input-signal coupling capacitors when the DC offset level of the input signals are within the range of 0.5V to (VCC - 1.2V). The MAX9718A EV kit also evaluates the MAX9718B, MAX9718C, and MAX9718D.
