An IC contains many discrete components (resistors, capacitors, and transistors) all made at the same time on the same piece of silicon and put into a standardized package. Op amps were originally developed as vacuum-tube circuits to be used for analog computation. Its output signal can be input signal addition, subtraction or differentiation, integration, etc, which early used in analog computers to do mathematical operations. ��i@�B�|�N�4 H�e+�" �< � �/�Uy�@~�G�@>:x� r�����A�e*�fb�������% Tм x�b``c``{����x=�A���b�,k8�$�������2�ª��4n�����,��P�$�����O֦�I�㒪�\W�D��s v&-圤Tps���"��Z)��Z؃�f����(�vV�`�Q)���c���D�;z+�R:�8uJ�����,�dO#�����EG��U\��6I9r�J��9�K��.
