I found the following circuit symbol in an MSP430 User's Guide in the section describing the ADC:
(I made a red circle around it)
What does it represent?
Electronic – What does this schematic symbol mean? (triangle with a line crossing it out)

This device is a transient voltage suppressor for USB D+ and D- signals. It protects the device from static voltages that may develop when inserting or removing USB devices to connectors.
The four diodes (on side) act as clamping diodes that conduct to suppress ESD.

It's the symbol of a current source.
There are different symbols used to represent a current source:

The diagram on page 631 of the user guide has it labeled "Temp. Sensor".
This is the internal Block Diagram for the SD24_A ADC, but it's almost functionally the same for the other ADC Types
