AMPLIFIER AND CURRENT
CONTROLLER
DESCRIPTION
The UM603 is a monolithic IC that includes one
independent op-amp and another op-amp for witch
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 systems
