Power Supplies
The PHI provides multiple power-supply options for the EVM, derived from the computer's USB supply.
The EEPROM and microSD card on the ADS9110EVM use a 3.3-V power supply generated directly by
the PHI. The ADC and analog input drive circuits are powered by the TPS7A4700 onboard the EVM,
which is a low-noise linear regulator that uses the 5.5-V supply out of a switching regulator on the PHI to
generate a much cleaner 5-V output. The 1.8-V supply to the digital section of the ADC is provided directly
by an LDO on the PHI.
The power supply for each active component on the EVM is bypassed with a ceramic capacitor placed
close to that component. Additionally, the EVM layout uses thick traces or large copper fill areas where
possible between bypass capacitors and their loads to minimize inductance along the load current path.

ADS9110EVM-PDK Initial Setup
This section explains the initial hardware and software setup procedure that must be completed for the
proper operation of the ADS9110EVM-PDK.
5.1
Default Jumper Settings
Jumper settings are determined by common mode and source impedance of the external source that
provides a differential signal to the board. Remove shunts from J4 and J6 and set J2 and J1 according to
the external source as described in
5.2
EVM Graphical User Interface (GUI) Software Installation
The EVM also comes with the microSD card pre-installed in slot J6. The microSD card contains the EVM
GUI installer that must be executed to install the EVM GUI software on the user's computer.
Manually disable any antivirus software running on the computer before
connecting the SD card or downloading the EVM GUI installer onto the local
hard disk. Otherwise, depending on the antivirus settings, an error message
such as the one shown in
deleted.
Download the latest version of the installer from the Tools and Software folder of the ADS9110 and run
the GUI installer. Accept the license agreements and follow the on-screen instructions to complete the
installation.
