EVALUATION BOARD HARDWARE
POWER SUPPLY
To use the AD7156 evaluation board, make sure that the link on
the supply header (J7) is in place, either in V_EVB when using
the on-board voltage supply or in V_EXT when using an
external voltage source via J8.
In both cases, the LED labeled POWER on the board should
turn on when connected to either of the supply sources.
I
The AD7156 evaluation board allows different digital interface
configurations by redirecting the I
on J5.
Default
Links in the SDA and SCL positions of J5 connect the USB
microcontroller as the I
as shown in Figure 6. This allows easy use of the evaluation
board together with the PC software.
USB—External Connection
The AD7156 evaluation board allows customers to connect
their own specific AD7156 application board to Pin 6 and Pin 8
of J5. This enables customers, together with the PC evaluation
software, to evaluate their application hardware using the AD7156
evaluation board only as a USB-to-I2C digital interface as
shown in Figure 7.

External Connection—AD7156
The AD7156 evaluation board can be used for software develop-
ment by connecting a customer-specific external microcontroller
board to Pin 5 and Pin 7 of J5, as shown in Figure 8, using the
AD7156 CDC on the evaluation board as the sensing device.
