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 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.
Figure 2 shows the BOOSTXL-ADS1219 EVM architecture along with key components and blocks listed in
the features.

Quick Start
2 Quick Start
The quick start in Figure 3 shows a minimalist view of the startup procedure to get the system up and
running. Details regarding these steps can be found in Section 4.
www.ti.com
Figure 3. Quick Start
2.1 Step 1
Download and install the GUI software from the BOOSTXL-ADS1219 tools folder. This software install
also includes the firmware file required for communication with the LaunchPad™. The firmware file can be
installed to the LaunchPad™ by using the UniFlash cloud tool. A desktop version of UniFlash is also
available for download if needed.
2.2 Step 2

When the desired firmware is selected, use the Load Image button to load the firmware into the
LaunchPad™.
Verify that the firmware installed successfully by checking the Console portion of the UniFlash tool at the
bottom of the GUI window.
2.3 Step 3
After the firmware file has successfully downloaded to the LaunchPad™, unplug the USB cable from the
LaunchPad™. Further communication takes place using the USB connector located at the opposite end of
the LaunchPad™. For proper power to be supplied to the BOOSTXL-ADS1219, remove the jumper from
the middle of the LaunchPad™ at JP6 and place the jumper on the center pins of JP1 (see Figure 12).
This jumper takes the available USB power from the bottom connector and applies the voltage to the
remainder of the board.
Before plugging the USB cable to the bottom LaunchPad™ USB connector, properly align the connectors
and attach the BOOSTXL-ADS1219 BoosterPack™ to the bottom set of connectors on the LaunchPad™
(Figure 4).
Quick Start
When the BoosterPack™ is attached, plug the USB cable into the bottom connector of the LaunchPad™
and also to the PC. The LaunchPad™ communication to the PC is USB communications device class
(CDC) using a virtual COM port. Windows®10 automatically installs the required driver. Earlier versions of
the operating system may require a manual driver installation. The required driver files can be found in the
installation directory Program Files (x86)/Texas Instruments/ADS1219/drivers.
2.4 Step 4
From the Windows Start menu, go to the Texas Instruments folder and under ADS1219 start the GUI

BOOSTXL-ADS1219 Hardware Overview
3 BOOSTXL-ADS1219 Hardware Overview
This section lists various onboard components that are used to interface analog inputs, analog reference,
digital interface, and power to the BOOSTXL-ADS1219 EVM. Figure 5 shows a top-level view of the
board.
www.ti.com
Figure 5. BOOSTXL-ADS1219 Overview
3.1 Connectors for the Analog Input
The BOOSTXL-ADS1219 EVM is designed for easy interface to analog sources through a 100-mil header
(J5) or to a screw terminal block (J6). J6 also allows for an external reference input. Table 2 shows the
input configuration for J5 and Table 3 shows the configuration for J6. Both connectors are clearly labeled
on the PCB silkscreen for easy input connection identification.

The analog inputs can range from GND up to AVDD, which is the analog supply voltage. A maximum of
four single-ended inputs, or two differential inputs may be applied to the ADS1219. The user can configure
the input channels through the ADS1219 BoosterPack™ GUI. Each of the analog inputs have a series 1kΩ resistor with a 100-nF differential capacitor between inputs and a 10-nF common-mode capacitor to
GND for filtering noise and aliasing. Figure 23 provides a schematic that details the input filtering.
3.2 Voltage Reference
The ADS1219 contains an internal 2.048-V reference and no external reference is required. The analog
supply can also be used as reference input by installing a 0-Ω resistor at R7. An external reference can be
applied to the terminal block REFP and REFN connections available on J6 (see the analog input terminal
block in Figure 5). The external reference input is limited by a minimum of 0.75 V and a maximum of the
analog supply voltage (AVDD). The REFN input is connected to the board ground by default through the
0-Ω resistor R8.
3.3 Digital Interface
The BOOSTXL-ADS1219 interfaces to the MSP-EXP432E401Y LaunchPad™, which in turn
communicates with the computer through USB. The two devices are on the BoosterPack™ and they both
communicate using I2C. U4 is an EEPROM used to hold device and board manufacturing information. The
EEPROM information is not currently available to the GUI. U1 is the ADS1219 and communication from
the GUI allows for register read and write as well as ADC conversion data collection.
3.4 BOOSTXL-ADS1219 Digial I/O
The BOOSTXL-ADS1219 EVM supports the I2C digital interface and functional modes as described in the
ADS1219 datasheet. The LaunchPad™ operates at a 3.3-V logic and I/O level. The ADS1219 has both
DVDD and AVDD. DVDD is the digital supply and is fixed to the same voltage level as the LaunchPad™
processor so no level shifting is required. The I2C communication is through LaunchPad™ ports PN5
(SCL) and PN4 (SDA). GPIO pin control for the Reset pin of the ADS1219 is controlled by port PK6. The
Reset control pin defaults high (not in reset). GPIO port PK7 is an input port pin used to interrupt the
processor when a new conversion result is ready to be read from the ADS1219. Table 4 lists the port to
connector pin interface.

BOOSTXL-ADS1219 Hardware Overview
3.5 Power Supply
Both the LaunchPad™ 3.3-V and 5-V supplies are used for the BOOSTXL-ADS1219. The digital supply is
3.3 V and supplies the ADS1219 DVDD supply input. AVDD is the ADS1219 analog supply and can
accommodate either 3.3-V or 5-V operation. The choice of analog supply voltage is selected by jumper
JP2. JP2:1-2 selects the 5-V supply source and JP2:2-3 selects the 3.3-V source, as shown in Figure 6.
www.ti.com
Figure 6. Analog Supply Jumper
The 3.3-V source comes directly from the LaunchPad™ and when available on the BOOSTXL-ADS1219
the D2 LED lights up indicating that the supply is active. The LaunchPad™ 5-V source is often less than
5 V. To achieve a stable voltage when operating at 5-V AVDD, U3 is used to charge pump the
LaunchPad™ 5-V source and regulate for a fixed 5-V output. U3 can be disabled by installing jumper JP1,
but by default this jumper is not installed. When U3 is active, then LED D1 lights up indicating the supply
is available. TP1 can be used to monitor the AVDD supply voltage. Jumper placement and LEDs are
shown in Figure 6.
4 Setup Details
