Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
ESD (electrostatic discharge) sensitive device. Extensive use may cause permanent damage to the device. Exposure to any Absolute of ESD protection devices are used internal to the LT1490A/LT1491A. Maximum Rating condition for extended periods may affect device However, high electrostatic discharge can damage or degrade the device. reliability and lifetime. Use proper ESD handling precautions.
Note 2:
A heat sink may be required to keep the junction temperature
Note 6:
VS = 5V limits are guaranteed by correlation to VS = 3V and below absolute maximum. This depends on the power supply voltage and VS = ±15V tests. how many amplifi ers are shorted. The θJA specifi ed for the DD and DHC
Note 7:
VS = 3V limits are guaranteed by correlation to VS = 5V and package is with minimal PCB heat spreading metal. Using expanded metal VS = ±15V tests. area on all layers of a board reduces this value.
Note 8:
Guaranteed by correlation to slew rate at VS = ±15V and GBW
Note 3:
The LT1490AC/LT1491AC and LT1490AI/LT1491AI are guaranteed at VS = 3V and VS = ±15V tests. functional over the operating temperature range of – 40°C to 85°C.
Note 9:
This parameter is not 100% tested. The LT1490AH/LT1491AH are guaranteed functional over the operating temperature range of –40°C to 125°C.
Note 4:
The LT1490AC/LT1491AC are guaranteed to meet specifi ed performance from 0°C to 70°C. The LT1490AC/LT1491AC are designed, characterized and expected to meet specifi ed performance from –40°C to 85°C but are not tested or QA sampled at these temperatures. The LT1490AI/LT1491AI are guaranteed to meet specifi ed performance from –40°C to 85°C. The LT1490AH/LT1491AH are guaranteed to meet specifi ed performance from – 40°C to 125°C. 14901afd 7 Document Outline FEATURES DESCRIPTION APPLICATIONS TYPICAL APPLICATION ABSOLUTE MAXIMUM RATINGS PIN CONFIGURATION ORDER INFORMATION ELECTRICAL CHARACTERISTICS TYPICAL PERFORMANCE CHARACTERISTICS APPLICATIONS INFORMATION TYPICAL APPLICATIONS SIMPLIFIED SCHEMATIC PACKAGE DESCRIPTION REVISION HISTORY TYPICAL APPLICATION RELATED PARTS
