In the middle we have a MAXIM 9776E that i cant find any info on

To the left theres a Texas Instruments TLV274I 3 MHz 4 channel rail to rail op amp

EDIT: After realizing i had a typo in the name, calling it an 9779E instread of the 9776E, its a 1.5W audio amp. this is used for vehicles where when using the RR you keep the original warning and door chimes but connecting a small speaker somewhere, usually shoved into the dash board.
