EVM Operation

Figure 6. Jumper J19

The following section provides information on the analog input, digital control, and general operating

conditions of the ADS1274EVM.

The analog input sources (channels 1-4) can be applied directly to J9 (top or bottom side) or through

signal-conditioning modules available for the the modular EVM system. Terminal block J7 is connected in

parallel with the analog signal connections to J9.

Each input signal can be selected to connect directly to the analog inputs of the ADS1274 or they can use

the OPA1632 buffers that are provided. Switches S2-5 can be switched away from the ADS1274 to select

the Terminal Block (TBK) or towards the ADS1274 to select the Amplifier (AMP) for the analog inputs 1

through 4 as shown in Figure 7.
