The LT1097 is pin compatible to and directly replaces such
precision op amps as the OP-07, OP-77, AD707, OP-97, OP-
177, LM607 and LT1001 with improved price/performance.
Compatibility includes externally nulling the offset voltage, as
all of the above devices are trimmed with a potentiometer
between Pin 1 and Pin 8 and the wiper tied to V
+
.
The simple difference amplifier can be used to illustrate
the all-around excellence of the LT1097. The 50k input
resistance is selected to be large enough compared to
input signal source resistance. Simultaneously, the 50k
resistors should not dominate the precision and noise
error budget. Assuming perfect matching between the
four resistors, the following table summarizes the input

other popular, low cost precision op amps.

with a 10k potentiometer.
The LT1097 is internally compensated for unity gain
stability. As shown on the Capacitive Load Handling plot,
the LT1097 is stable with any capacitive load. However,
the overcompensation capacitor, C
S
, can be used to re-
duce overshoot with heavy capacitive loads, to narrow
noise bandwidth or to stabilize circuits with gain in the
feedback loop.
