MAX98309 Evaluation Kit
Evaluates: MAX98309/MAX98310
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.
