APPLICATIONS INFORMATION
Application Notes and Test Circuits
The LT1001 series units may be inserted directly into
OP-07, OP-05, 725, 108A or 101A sockets with or without
removal of external frequency compensation or nulling
components. The LT1001 can also be used in 741, LF156
or OP-15 applications provided that the nulling circuitry is
removed.
The LT1001 is specified over a wide range of power supply
voltages from ±3V to ±18V. Operation with lower supplies
is possible down to ±1.2V (two Ni-Cad batteries). How-
ever, with ±1.2V supplies, the device is stable only in
closed loop gains of +2 or higher (or inverting gain of one
or higher).

Unless proper care is exercised, thermocouple effects
caused by temperature gradients across dissimilar metals
at the contacts to the input terminals, can exceed the
inherent drift of the amplifier. Air currents over device
leads should be minimized, package leads should be
short, and the two input leads should be as close together
as possible and maintained at the same temperature.
