The MAX9730 evaluation kit (EV kit) is a fully assembled

and tested PCB that uses the MAX9730 Class G power

amplifier to drive a bridge-tied-load (BTL) speaker in

portable audio applications. Designed to operate from

a 2.7V to 5.5VDC power supply, the EV kit accepts a

single-ended or differential input signal. The EV kit pro-

vides a fully differential output capable of delivering

2.4W into an 8Ω speaker.
