GMA103A

DUAL OPERATIONAL AMPLIFIER AND VOLTAGE REFERENCE

Gamma Microelectronics Inc. 

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.
