Low Cost, Low Power
Precision Op Amp

DESCRIPTION
LT®1097 achieves a new standard in combining low price
and outstanding precision performance.
On all operational amplifier data sheets, the specifications
listed on the front page are for highly selected, expensive
grades, while the specs for the low cost grades are buried
deep in the data sheet.
The LT1097 does not have any selected grades, the
outstanding specifications shown in the Features section
are for its only grade.
The design effort of the LT1097 concentrated on optimizing the performance of all precision specs—at only 350µA
of supply current. Typical values are 10µV offset voltage,
40pA bias and offset currents, 0.2µV/°C and 0.4pA/°C
drift. Common mode and power supply rejections, voltage
gain are typically in excess of 128dB.
All parameters that are important for precision, low power
op amps have been optimized. Consequently, using the
LT1097 error budget calculations in most applications is
unnecessary.

APPLICATIONS INFORMATION
The LT1097 is pin compatible to and directly replaces such
precision op amps as the OP-07, OP-77, AD707, OP-97, OP177, 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

referred performance obtained using the LT1097 and
other popular, low cost precision op amps.
Input offset voltage can be adjusted over a ±600µV range
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, CS, can be used to reduce overshoot with heavy capacitive loads, to narrow
noise bandwidth or to stabilize circuits with gain in the
feedback loop.

APPLICATIONS INFORMATION
The availability of the compensation terminal permits the use
of feedforward frequency compensation to enhance slew
rate. The voltage follower feedforward scheme bypasses the
amplifier’s gain stages and slews at nearly 10V/µs.
The inputs of the LT1097 are protected with back-to-back
diodes. In the voltage follower configuration, when the
input is driven by a fast, large signal pulse (>1V), the input

protection diodes effectively short the output to the input
during slewing, and a current, limited only by the output
short circuit protection will flow through the diodes.
The use of a feedback resistor, as shown in the voltage
follower feedforward diagram, is recommended because
this resistor keeps the current below the short circuit limit,
resulting in faster recovery and settling of the output.
