EVAL-ADM1175/ADM1176/ADM1177/ADM1178
EVALUATING MULTIPLE DEVICES IN PARALLEL
In the case of the ADM1175, ADM1177, and ADM1178, up to
four unique I
connect up to four devices. In the case of the ADM1176, up to
16 I
to 16 ADM1176 devices.
Each evaluation board is fitted with switches labeled A0 and A1.
A0 is used on the ADM1175/ADM1176/ADM1177/ADM1178
devices to assign an address, via the ADR pin, to that particular
device. For the ADM1176, A1 is also used in combination with
A0 to assign up to 16 I
a unique I
When interconnecting the ADM1175/ADM1176/ADM1177/
ADM1178 devices, each device is powered using a bench
supply of between 3.15 V and 16.5 V, connected to J3 (VIN)
and J4 (GND).
The first evaluation board should be connected to the PC using
a 5-pin SMBus cable from the 5-pin header labeled J7. Each
board is fitted with two MiniMolex® interconnecters, J8 and J9.
To interconnect multiple boards use the provided red 5-pin
MiniMolex cables.

Figure 39 displays the result of the device address search when
four ADM1175/ADM1176/ADM1177/ADM1178 boards have
been cascaded. Note that the I
are highlighted in green.
Click OK to access the Sense Resistor Value window (see
Figure 40). Enter the value of the current-sense resistors; the
default value of R3 is 0.2 Ω.

Click OK and the evaluation software Main Panel appears (see
Figure 41).
Note the presence of a drop-down menu entitled Device
selector (see Figure 42).
The Device selector drop-down menu allows you to select each
device individually and select the configuration settings for that
device. Select the range and reading method then click Write
Data To Command Register to pass the change to the register
of the device.
The voltage, current, and power graphs can be viewed by
selecting the V, I & P graphs 1-4 tab.
