ADS1220EVM
Using the ADS1220EVM ADCPro Plug-in
The IDAC Magnitude drop-down menu allows the choice of current settings for the constant-current
output digital-to-analog converters (DACs) of the ADS1220. Two current output DACs are available and
can be routed independent of one another through the IDAC 1 Routing and IDAC 2 Routing controls.
However, the IDAC Magnitude is the same for both current sources and the current output is not
independently controlled. No current sources from the IDACs if the IDAC Magnitude is Off. This condition
is true even if the IDAC routing controls have the IDACs routed to a specified output. The seven output
current magnitude options are 10uA, 50uA, 100uA, 250uA, 500uA, 1000uA, and 1500uA. If both IDACs
are routed to the same output, the IDAC current available is twice the indicated IDAC Magnitude.

The IDAC current sources can be routed independently or to the same output. The control for the IDAC 1
Routing and IDAC 2 Routing have the same drop-down menu options. If the IDAC routing is Off, then
the IDAC being controlled is disabled and no current is sourced. This condition is true even if the IDAC
Magnitude indicates an available current. The IDAC current can be routed out through any of the analog
or reference input channels.
