SOP-14
LINEAR INTEGRATED CIRCUIT
DESCRIPTION
UTC LM224 consist of four independent, high-gain, frequency-
compensated 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.
