DESCRIPTION
UTC LM224 consist of four independent, high-gain, frequencycompensated operational amplifiers which are designed to operate
from a single power supply over a wide range of voltage. Operation
from split supplies is also possible so long as the difference
between the two supplies is 3V ~ 30V. The low supply current drain
is independent of the magnitude of the supply voltage.
The device can easily be implemented in single supply voltage
system, including transducer amplifiers, DC gain blocks, and all of
conventional OP Amp circuits.

Notes: 1. All voltage values(except differential voltages and VCC specified for the measurement of IIN(OS) are with
respect to the network GND.
2. Differential voltages are at IN+ with respect to IN-.
3. Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
4. The device is guaranteed to meet performance specification within 0°C ~70°C operating temperature
range and assured by design from –25°C ~+85°C.
