BOOSTXL-ADS1219 TI数据采集扩展板DEVELOPMENT DATA ACQUISITION

　　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 MSPEXP432E401Y) must be used. The LaunchPad? communicates to the ADS1219 through its I2C 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 I2C 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.

　　? I2C interface for the ADS1219 device configuration and communication.
