Can't find a datasheet, for the TK0373E

hello, I am converting a bluetooth speaker into a wired one (dont ask why lol)
I need a datasheet to find the input pins of the amp, to connect my aux cable to. the (TK0373E. )
I saw a post on the TK0577E where somebody said its the same chip as the PAM8406 stereo AB/D amp chip which has a readily available datasheet

can anyone help me find what chips are the same as the TK0373E so I can get a datasheet?
