DESCRIPTION
The TSM103W 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 offers both
space and cost savings in many applications such
as 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 V
CC+
- 1.5V. Both inputs can go to Vcc+ 0.3V without damage.
