DUAL OPERATIONAL
AMPLIFIER AND CURRENT
CONTROLLER
DESCRIPTION
The UTC
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 management or data acquisition systems
LINEAR INTEGRATED CIRCUIT

Note: 1. The input common-mode voltage 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
goto +36V without damage.
2. The dynamic impedance is defined as「ZKA」=△kA/△Ik
