Description
D u a l O p e r a t i o n a l A m p l i f i e r a n d Vo l t a g e R e f e r e n c e
The GSC103A is a monolithic IC that includes one independent op-amp and another op-amp foe 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 system.

Note1: The 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 input can go to +36V without damage.
