Description
GMA103A is a monolithic IC that includes one independent
op-amp and another op-amp, for which the non inverting in-
put 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 VCC + - 1.5V.
But either of both inputs can go to +36V without damage.
