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.

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 VCC+ - 1.5V.
But either of both inputs can go to +36V without damage.
