DESCRIPTION
The TSM103 is a monolithic IC that includes one
independent op-amp and another op-amp for
which the non inverting input is wired to a 2.5V fixed
Voltage Reference. This device is offering space
and cost saving in many applications like power
supply management or data acquisition systems.

Note 1
:
The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper
end of the common-mode voltage range is V
CC+
-1.5V
But either of both inputs can go to +36V without damage.
