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 mana-
gement or data acquisition systems
FEATURES
OPERATIONAL AMPLIFIER

*Low supply current: 350uA/op.(@ Vcc= 5 V)
*Medium bandwidth(unity gain): 0.9MHz
*Large output voltage swing: 0 V to (Vcc-1.5 V)
*Input common mode voltage range includes ground
*Wide power supply range: 3V to 32V
1.5 TO 16V
VOLTAGE REFERENCE
*Fixed output voltage reference 2.5V
*Sink current capability : 1 to 100mA
*Typical output impedance : 0.2
