Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Connecting any terminal to voltages greater than V+ or less than
V– may cause destructive latchup. It is recommended that no sources
operating from external supplies be applied prior to power-up of the
LTC1050.
Note 3: These parameters are guaranteed by design. Thermocouple effects
preclude measurement of these voltage levels in high speed automatic test
systems. VOS is measured to a limit determined by test equipment
capability.
Note 4: Current Noise is calculated from the formula: In = √(2q • Ib)
where q = 1.6 • 10–19 Coulomb.
Note 5: At TA ≤ 0°C these parameters are guaranteed by design and not
tested.
Note 6: Every lot of LTC1050AM and LTC1050AC is 100% tested for
Broadband Noise at 1kHz and sample tested for Input Noise Voltage at
0.1Hz to 10Hz.
