BOOSTXL-ADS1219 BoosterPack™ User's Guide
1 Introduction
The BOOSTXL-ADS1219 is a fully-assembled evaluation platform designed to highlight the ADS1219
device features and its various modes of operation.
The BOOSTXL-ADS1219 interfaces to LaunchPad™ development platforms using the XL connector
format. However, to use the ADS1219 BoosterPack™ GUI a specific LaunchPad™ (the MSP-
EXP432E401Y) must be used. The LaunchPad™ communicates to the ADS1219 through its I
2
C interface
and also acts as a USB-to-PC GUI communication bridge.
NOTE: The BOOSTXL-ADS1219 requires an external master controller to evaluate the ADS1219.
The MSP-EXP432E401Y LaunchPad™ is controlled by commands received from the ADS1219
BoosterPack™ GUI. The LaunchPad™ sends data to the GUI for display and analysis. If a LaunchPad™
is not used, the BoosterPack™ plug-in module format allows an alternate external host to communicate
with the ADS1219 using the LaunchPad™ connectors.
The BOOSTXL-ADS1219 EVM incorporates circuitry and components with the following features:
• The 24-bit ADS1219 delta-sigma ADC with four single-ended input channels (or two differential),
2.048-V reference, and I
2
C interface.
• External reference and analog inputs can be connected either through a header or screw terminal
block.
• 3.3-V or 5-V selectable analog power supply.
• LEDs to indicate active power supplies.
• I

C interface for the ADS1219 device configuration and communication.
