Product Details
The MAX9719A evaluation kit (EV kit) is a fully assembled and tested circuit board that uses the MAX9719A stereo, differential audio amplifier to drive a pair of bridge-tied-load (BTL) speakers in portable audio applications. Designed to operate from a 2.7V to 5.5V DC power supply, the EV kit is capable of delivering 2 x 1.1W into a pair of 8Ω speakers.
The MAX9719A inputs can accept a common-mode input voltage of 0.5V through (VCC - 1.2V) from a DC-coupled 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 is within an acceptable range. The MAX9719A EV kit also evaluates the MAX9719B, MAX9719C, and MAX9719D.
