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.
