Power supply and null pot connections for TO-5 metal-can packageand 8-lead DIP package are shown. Maximum rated power supply voltages are ±18 V, but lower voltages may be used. 9-V transistor battery is often used for each supply, but higher voltages will permit larger output signal swing. Pin 3 is inverting input, and pin 4 is noninverting input.With values shown, both input terminals see about same resistance. and output offset can be nulled to zero. Gain of circuit is about l00.-C.
