3 / 24 page  LTC1052/LTC7652 3 1052fa ELECTRICAL CHARACTERISTICS Note 1: Absolute Maximum Ratings are those 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 cause 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: These parameters are guaranteed by design. Thermocouple effects preclude measurement of the voltage levels in high speed automatic testing. VOS is measured to a limit determined by test equipment capability. Voltages on CEXTA and CEXTB, AVOL, CMRR and PSRR are measured to insure proper operation of the nulling loop to ensure meeting the VOS and VOS drift specifications. See Package-Induced VOS in the Applications Information section. Note 4: Output clamp not connected. Note 5: Current noise is calculated from the formula: in = (2q IB)1/2, where q = 1.6 • 10–19 coulomb. TYPICAL PERFOR A CE CHARACTERISTICS The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VS = ±5V, test circuit TC1, unless otherwise noted.
