ELECTRICAL CHARACTERISTICS

Note 3:
10Hz noise voltage density is sample tested on every lot of A listing and parameters. grades. Devices 100% tested at 10Hz are available on request.
Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
This parameter is tested on a sample basis only. may cause permanent damage to the device. Exposure to any Absolute
Note 5:
Current noise is calculated from the formula: in = (2qlB)1/2, where Maximum Rating condition for extended periods may affect device q = 1.6 • 10–19 coulomb. The noise of source resistors up to 1GΩ swamps reliability and lifetime. the contribution of current noise.
Note 2:
Offset voltage is measured under two different conditions:
Note 6:
Offset voltage drift with temperature is practically unchanged when (a) approximately 0.5 seconds after application of power; (b) at TA = 25°C the offset voltage is trimmed to zero with a 100k potentiometer between only, with the chip heated to approximately 38°C for the LT1055 and to the balance terminals and the wiper tied to V+. Devices tested to tighter 45°C for the LT1056, to account for chip temperature rise when the device drift specifications are available on request. is fully warmed up.
