Hi Nishmitha,
Which thermal values are you looking for? The most common requirement is for package thermal impedance (theta_JA) and that is available in the datasheet.

I am looking for power dissipation,thermal resistance for junction to case and maximum junction temperature.

The junction temperature is provided only as an absolute max value beyond which there can be reliability and performance issues with the device.
The Tj max is rated at 150C
The power dissipation can be calculated as per the application note www.ti.com/.../scaa035b.pdf
