Note 6: G = 10 limits are guaranteed by correlation to G = 1 tests and gain Note 2: ESD (Electrostatic Discharge) sensitive device. Extensive use of error tests at G = 10. ESD protection devices are used internal to the LT1990, however, high Note 7: Limits are guaranteed by correlation to –5V to 80V CMRR tests. electrostatic discharge can damage or degrade the device. Use proper ESD Note 8: VS = 3V limits are guaranteed by correlation to VS = 5V and handling precautions. VS = ±15V tests.
