Datasheet

The EV kit incorporates jumpers JU2 and JU4–JU7 to set
the output scale factor. See Tables 2 and 3 for setting the
output scale factor for the MAX4206 and MAX4207.
Jumper JU8 controls the REFIIN pin of the MAX4206/
MAX4207 device. See Table 4 for JU8 function.
The EV kit incorporates jumper JU11 to create a con-
nection between CMVIN and CMVOUT pins. To set the
common-mode voltage input to a voltage other than
0.5V (MAX4206) or 0V (MAX4207), remove the shunt
across JU11, and then connect a desired common-
mode voltage on the CMVIN pad.
Output Offset (MAX4206)
To adjust the output offset voltage for single-supply
operation, cut open the short on R14, install a resistor
on the R14 pads, and then apply a current on the
OSADJ pad. The value of R14 can be calculated by the
following equation:
R14 = V
OS
/ I
OSADJ
where V
OS
is the desired offset voltage, and I
OSADJ
is
a user-supplied offset current.
Evaluating the MAX4207
To evaluate the MAX4207 with the MAX4206 EV kit,
replace the MAX4206ETE with a MAX4207ETE, replace
R1, R2, C7, and C8 with component values 330Ω,
330Ω, 33pF, and 33pF, respectively.
Jumper JU1 must be open to ensure proper operation
with dual supplies.

REFIIN PIN
Pins 1 and 2
REFIIN is connected to the REFIIN pad,
requiring an external reference source.
Pins 2 and 3
REFIIN is connected to the REFIOUT pad,
using the internal reference current source.
