UTC UM603/A LINEAR INTEGRATED CIRCUIT
DUAL OPERATIONAL
AMPLIFIER AND CURRENT
CONTROLLER
DESCRIPTION
The UM603/A 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 mana-
gement or data acquisition systems
SOP-8

1.The input common-mode votage 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.
