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.
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.
