Schematics and Layout www.ti.com
Schematics for the ADS1672EVM are appended to this user's guide. The bill of materials is provided in
Table 6 .
Note: Board layouts are not to scale. These figures are intended to show how the board is laid out;
they are not intended to be used for manufacturing ADS1672EVM PCBs.
Note: All components should be compliant with the European Union Restriction on Use of
Hazardous Substances (RoHS) Directive. Some part numbers may be either leaded or
RoHS. Verify that purchased components are RoHS-compliant. (For more information about
TI's position on RoHS compiance, see the Quality and Eco-Info information on the TI web
site .)
