INA223EVM Software Overview

5.2 Configuring the INA223 Software

The next steps of this user’s guide describes how to configure the software and hardware for different

configurations.

5.2.1 I

C Address Selection

The INA223 has a flexible I

C address configuration that allows for multiple devices to be on the same I

lines. By moving the A0 address on jumpers JMP1 and JMP2 to either GND, VS, SDA or SCL, the INA223

can be changed to four different I

C addresses, as shown in Table 4.

Table 4. INA223 I

C Address Configuration

A0 Address

GND 1000000

VS 1000001

SDA 1000010

SCL 1000011

Figure 16 shows how to configure the I

C addresses. Click on the I

C Address Select button (shown in the

red box) to select how the hardware is configured on the EVM. If the correct address is not selected, the

INA223 cannot communicate with the software.
