Figure 3. ADS1258EVM Default Jumper Locations
The jumpers on J4 provide a convenient way to measure the current for any of the power-supply currents:
AVDD (analog +V power), DVDD (digital power), AVSS (analog –V power), or the ground connections
VGND and DGND. Simply remove the jumper for the appropriate power supply and use a current meter
between the jumper pins. The supply voltage for the digital supply (DVDD) can also be selected to be
either 1.8V or 3.3V; see Table 6.
Table 8 provides a list of switches found on the EVM and the factory default conditions for each one.
