DESCRIPTION
LT
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 optimiz-
ing the performance of all precision specs—at only 350 A
of supply current. Typical values are 10 V offset voltage,
40pA bias and offset currents, 0.2 V/ 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.

... U U APPLICATIONS INFORMATION 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 voltage follower feedforward scheme bypasses the amplifier’s gain stages and slews at nearly 10V/ s. 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 ...
