DESCRIPTION
The KL103/A is a monolithic IC that includes one independent op-amp and another op-amp for which 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.

* Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device.
These are stress ratings only and functional operation of the device at these or any other conditions beyond those
indicated under “recommended operating conditions” is not implied.
Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

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 go to +36V without damage.
