Note 2: Connecting any terminal to voltages greater than V+ or less than Note 5: At TA ≤ 0°C these parameters are guaranteed by design and not V– may cause destructive latchup. It is recommended that no sources tested. operating from external supplies be applied prior to power-up of the Note 6: Every lot of LTC1050AM and LTC1050AC is 100% tested for LTC1050. Broadband Noise at 1kHz and sample tested for Input Noise Voltage at Note 3: These parameters are guaranteed by design. Thermocouple effects 0.1Hz to 10Hz. preclude measurement of these voltage levels in high speed automatic test systems. VOS is measured to a limit determined by test equipment capability. 1050fb 3
