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 optimiz-
ing 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
