Default Jumper Settings

After unpacking, the EVM is already configured with the default jumper settings. Figure 5 shows the locations for the default jumpers.

default_jumpers_sbau352.gifFigure 5. ADS131B04-Q1EVM Jumper Default Settings

The default position of the JP6 jumper is across [1-2] at the top. JP6 sets the onboard oscillator frequency to 8.192 MHz, used for the ADS131B04-Q1 in high-resolution mode. The default connection for JP9 is to the left, so that the linear regulator is powering the system using 5 V from the PHI controller.

The default settings, as listed in Table 8, includes no jumpers installed at JP5, JP7, and JP8. When installed, JP5 disables the onboard oscillator, JP7 enables the EEPROM for write, and JP8 disables the linear regulator.

Table 8. Default Settings

Jumper Position Function
JP1, JP2, JP3, JP4 [3-4] Sets common-mode to ground for device inputs
JP5 Not installed Disables on-board oscillator
JP6 [1-2] Oscillator frequency select, 8.192MHz
JP7 Open Disables write for EEPROM
JP8 Not installed Disables linear regulator power
JP9 [1-2] Selects device power from linear regulator
