programmable gain amplifier basics

The voltage gain for the same is given as The magnitude of gain A is |A|=|2πfRC| Thus the gain A is directly proportional to frequency f. At low frequency, the gain is also low. %�� These ICs incorporate all of the gain-setting components and can be programmed to eight different gain settings using three digital control inputs. 0000010251 00000 n /atilde /aring /ccedilla /eacute /egrave /ecircumflex /edieresis ��c.��"��)�Nh'��Wm9�]D�m6v��dm��lYt�rP��7 ]Va3�ځȵA߽�^p5i��҃�� 7�l�~%V��P׎��E�-�k�)d�=�7��'�Ķ�ȟ��S��xm9��`��+C�\yO�$�NC]-vB�g�^7�ߵ��S�!&n�6Ǿ�� r�;l�\İ�;�u��]~z�:3�I��pǻ�k�U�8b�i$ ��v�I��z~�|}�� s��W ��A�� 5K�B]Z��8��$�ED��]�O�l��./�)A?
