Introduction

　　The ADS7128 BoosterPack?is a fully-assembled evaluation platform designed to highlight the ADS7128 features and various modes of operations that make this device suitable for ultra-low-power, small-size sensor monitor applications.

　　The accompanying MSP432E401Y LaunchPad?development kit (MSP-EXP432E401Y) is used as a USB-to-PC GUI communication bridge. This kit also serves as an example implementation of a master microcontroller (MCU) to communicate with the ADS7128 through an I2C interface.

　　NOTE: The BP-ADS7128 requires an external master controller to evaluate the ADS7128.

　　The MSP-EXP432E401Y is controlled by commands received from the ADS7128 GUI, and returns data to the GUI for display and analysis. If the MSP-EXP432E401Y is not used, the BoosterPack?plug-in module format of the BP-ADS7128 board allows for an alternative external host to communicate with the ADS7128.

　　The BP-ADS7128 incorporates all required circuitry and components with the following features:

　　?ADS7128 low-power, ultra-small, eight-channel sensor monitor with I2C interface and alert output

　　?External power-supply connection available to provide 3.3 V to power the ADS7128 DVDD supply instead of the universal serial bus (USB) power from the MSP432E401Y LaunchPad?

　　?Optional adjustable linear regulator, TI’s TPS78001, to generate stable output voltage to power the ADS7128 AVDD and DVDD pins when using the 5-V USB power from the MSP432E401Y LaunchPad?

　　?I2C interface for communication and configuration of modes available on the ADS7128
