General Description

The MAX98309 evaluation kit (EV kit) is a fully assembled

and tested circuit board that evaluates the MAX98309

mono 1.4W Class AB audio amplifier. The amplifier gain

can be set through external resistors. The EV kit operates

from a single 2.5V to 5.5V power supply.

The EV kit can also evaluate the MAX98310 internally

fixed gain mono 1.4W Class AB audio amplifier.
