ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are tho values beyond which the life of a device may be impaired.
Note 2: Connecting any terminal to voltages greater than V +, or less than V –, may cau destructive latch-up. It is recommended that no sources operating from external supplies be applied prior to power-up of the LTC1052/LTC7652.
Note 3: The parameters are guaranteed by design. Thermocouple effects preclude measurement of the voltage levels in high speed automatic testing. V OS is measured to a limit determined by test equipment capability. Voltages on C EXTA and C EXTB , A VOL , CMRR and PSRR are
measured to insure proper operation of the nulling loop to ensure meeting the V OS and V OS drift s
pecifications. See Package-Induced V OS in the Applications Information ction.Note 4: Output clamp not connected.
Note 5: Current noi is calculated from the formula: i n = (2q I B )1/2, where q = 1.6 • 10–19 coulomb.
