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. T his device offers both
space and cost savings in many applications such
as power supply m anagemen t or data acqui sition
systems.
