The ADS1282EVM is designed for easy interfacing with analog sources. This section covers the details of the
front-end circuit, including jumper configurations for different input ranges and clock sources, as well as board
connectors for signal sources.
2.1 EVM Analog Input Options
Connect differential analog input signals to pins +AINx and -AINx (x denoting channels 1 and 2) of headers
J3 and J5. Enable single-ended inputs for channel 1 by connecting -AIN1 to system ground (short pins 2-3 of
header J3) and apply the signal to pin 1 of header J3. For channel 2, connect -AIN2 to system ground (short pins
1-2 of header J5) and apply the signal to pin 3 of header J5.
Each of the differential input pairs accepts up to a 5V
from 0V up to +2.5V. The
details.
