ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 6:
This parameter is not 100% tested. may cause permanent damage to the device. Exposure to any Absolute
Note 7:
The input voltage range is guaranteed by the ±15V CMRR tests. Maximum Rating condition for extended periods may affect device The Input Voltage Range numbers specified in the table guarantee that the reliability and lifetime. internal op amp operates in its normal operating region. The Input voltage
Note 2:
See Common Mode Voltage Range in the Applications Information range can be higher if the internal op amp operates in its Over-The-Top® section of this data sheet for other considerations when taking +INA/ operating region. See Common Mode Voltage Range in the Applications –INA/+INB/–INB/+INC/–INC pins to V– + 80V. Information section to determine the valid input voltage range under
Note 3:
A heat sink may be required to keep the junction temperature various operating conditions. below absolute maximum. This depends on the power supply, input
Note 8:
Input impedance is tested by a combination of direct voltages and the output current. measurements and correlation to the CMRR and gain error tests.
Note 4:
The LT1997I-1 is guaranteed functional over the operating
Note 9:
Offset voltage, offset voltage drift and PSRR are defined as temperature range of –40°C to 85°C. The LT1997H-1 is guaranteed referred to the internal op amp. The following shows the calculation of functional over the operating temperature range of –40°C to 125°C. output offset: In the case of balanced source resistance, VOS,OUT = (VOS
