The LT1097 does not have any selected grades, the

outstanding specifications shown in the Features section

are for its only grade.

Guaranteed Operation on Two NiCad Batteries

The design effort of the LT1097 concentrated on optimiz-

ingtheperformanceofallprecisionspecs—atonly350µA

of supply current. Typical values are 10µV offset voltage,

40pA bias and offset currents, 0.2µV/°C and 0.4pA/°C

drift. Commonmodeandpowersupplyrejections, voltage

gain are typically in excess of 128dB.

APPLICATIONS

■

Replaces OP-07/OP-77/OP-97/OP-177/AD707/

LT1001 with Improved Price/Performance

■

High Impedance Difference Amplifiers

Logarithmic Amplifiers (Wide Dynamic Range)

Thermocouple Amplifiers

Precision Instrumentation

Active Filters (with Small Capacitors)

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.
