Evaluates: MAX4208/MAX4209
MAX4208/MAX4209 IC data sheet for application
details. Verify that the selected resistor is rated for the
appropriate current and power levels.
For high-power applications, use the IN+ and IN- PCB
pads as sense connections to an off-board current-
sense resistor.
Differential Input Filter
The MAX4209 EV kit features an optional balanced-
differential resistor-capacitor filter across the MAX4209
IN+ and IN- input pins. Use the surface-mount 0603
PCB pads for installing resistors R5, R6, and capacitor
C7, which form the filter. Before installing resistors R5
and R6, cut open the shorting PCB trace located at the
respective pads.
Evaluating the MAX4208 and an Alternate
MAX4209
The MAX4209 EV kit can evaluate the adjustable-gain
MAX4208 and alternate-voltage-gain versions of the
MAX4209 in the 8-pin µMAX package by replacing the
IC (U1). Install gain-setting resistors R1 and R2 for
MAX4208 evaluation. The MAX4209 features alternate-
fixed gains of 10V/V or 1000V/V. See the
Part Selection
Table
for IC ordering information.
The MAX4208 EV kit is also available separately.
