Most of the Galaxy Tab A models do not support an MHL signal with an adapter between the micro-USB port to HDMI port. To connect it to a TV, you'd need a Chromecast or similar device connected to the HDMI port of the TV. Then connect your tablet to the Chromecast for screen-sharing. For some TVs with wi-fi, you can use the All-Share app instead.
This is the case for the Galaxy Tab A (2016) 10.1" model. I don't see any Galaxy Tab A devices with MHL support here:
http://www.mhltech.org/devices.aspx . Samsung stopped providing the MHL connections on most of the devices by 2015, depending on the country where the device was sold. See
http://blog.clove.co.uk/2014/02/05/mhl-adapter-samsung-galaxy-need/ . To check your device, look at the micro-USB port, if it has 11 pins then it might support MHL.
I wish that I had better news for you. Please add a comment with the generation/year of production for your Galaxy Tab A for further information about the specifications.
