9 / 26 page www.ti.com INA223EVM Hardware Overview 3.5 INA223EVM Default Jumper Settings Figure 8 shows the default jumper configuration for the INA223EVM. You may want to change some of the jumpers on the INA223EVM to match your specific configuration. For example, you may wish to set a specific I 2C address by configuring jumper 1 (JMP1) and jumper 2 (JMP2). Figure 8. INA223EVM Default Jumpers Jumper 3 (JMP3) on the INA223EVM is typically set to the internal (INT) position. When set to the INT position, the device supply voltage is generated and controlled from the SM-USB-DIG Platform. When this jumper is set to the external (EXT) position, INA223 pin 4 (V S) connects to terminal strip T1 and can be powered from an external supply. JMP1 and JMP2 control the I 2C address pin for the INA223; these jumpers set the address for A0 to either high, low, SCL, or SDA. Make sure to connect only one jumper at a time for the address control (for example, if JMP1 is connected, do not connect JMP2, and vice versa). Failure to properly connect jumpers can cause shorts or interruptions in the communication lines. For more information on the INA223 addressing, consult the INA223 data sheet (SBOS528). Table 3 summarizes the function of the INA223 test board jumpers. For most applications, all the jumpers should be left in their default configurations. Table 3. INA223 Test Board Jumper Functions Jumper Default Description JMP1 Open These jumpers select the I 2C AO address selection for A0. Four separate I 2C addresses can be selected,depending on whether JMP2 JMP2 GND is set to high or low, or JMP1 is set to SDA or SCL. JMP3 INT This jumper selects whether the V S pin on the INA223 is connected to the digital power-supply signal (VDUT) generated from the SM-USB- DIG Platform (INT position), or whether the VDUT pin is connected to terminal T1, thus allowing for an external supply to power the digital circuitry (EXT position). 9 SBOU125 – June 2012 INA223EVM User’s Guide and Software Tutorial Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated |
