2.1 As an Input to a Analog-to-Digital Converter EVM
Four three-terminal screw jacks (J5, J4, J3, and J2 are located on the top side
of the board to provide a convenient way to attach a variety of signal sources.
The screw jacks are arranged as a channel pair for the easy application of
differential or single ended analog sources. Single ended sources can be
applied to terminal 1 or 3, referenced to terminal 2. Differential sources can be
applied between terminals 1 and 3.
Figure 2-1. Application of Analog Source to ADC
When used with an analog-to-digital converter EVM, connector J1 (bottom
side of PCB) plugs into a male header located on the left edge of the interface
board. In this case, J1 acts as a support/stabilization mechanism. The output
from the signal conditioning board is available on J7 (top side —20 pin header,
bottom side—20 pin socket). The 20-pin socket portion of J7 plugs into the
analog I/O header located on the interface board.
