I am reversing a board which some of its IC labels are erased by the manufacturer. I've drowned its schematic in the picture below. The label-removed ICs in the schematic are IC5, IC8, and IC13 which are marked in the picture. The table of resistor values is attached and all of the electrolyte capacitors are 10uF 50V except C9, C10. I have also attached the pictures of the ICs on the board.
The board connects to a motherboard by a 3*32 pin connector which is shown by a rectangle sign with its number in the schematic. I found a text about this board that says the board's job is analog processing of values measured by other motherboard's cards.
From the schematic, I guess that IC13 is a kind of switch-mode power supply and IC5 is maybe a quad digital to analog converter. I searched in datasheets but still, I couldn't find any IC with input and output pins accorded to the schematic.
I hope you can help me to identify the marking code or the family of unknown ICs (IC5, IC8, IC13).
