POSITIVE FEEDBACK TO ONE OF THE NULLING TERMINALS
CREATES APPROXIMATELY 5µV OF HYSTERESIS.
OUTPUT CAN SINK 16mA.
INPUT OFFSET VOLTAGE IS TYPICALLY CHANGED LESS
THAN 5µV DUE TO THE FEEDBACK.

THE ADDITION OF THE LT1007 DOUBLES THE AMPLIFIER’S OUTPUT DRIVE
TO ±33mA. GAIN ACCURACY IS 0.02%, SLIGHTLY DEGRADED COMPARED
TO ABOVE BECAUSE OF SELF-HEATING OF THE LT1037 UNDER LOAD.
