Is there an exposed substrate pad on the bottom of the OPA1688 SOIC-8 package?

There is not an exposed substrate pad on the SOIC-8 package.

Can the WSON-8 substrate PAD be connected to GND?

The thermal pad should be tied to the most negative supply. Please see the related post for more information.
