Note 1:
Absolute Maximum Ratings are those values beyond which the
Note 4:
This parameter is tested on a sample basis only. life of a device may be impaired.
Note 5:
Current noise is calculated from the formula: in = (2qIB)1/2, where
Note 2:
Offset voltage is measured under two different conditions: q = 1.6 • 10 –19 coulomb. The noise of source resistors up to 1GΩ swamps (a) approximately 0.5 seconds after application of power; the contribution of current noise. (b) at TA = 25°C, with the chip self-heated to approximately 45°C
Note 6:
Offset voltage drift with temperature is practically unchanged when to account for chip temperature rise when the device is fully warmed up. the offset voltage is trimmed to zero with a 100k potentiometer between
Note 3:
10Hz noise voltage density is sample tested on every lot of A the balance terminals and the wiper tied to V +. Devices tested to tighter grades. Devices 100% tested at 10Hz are available on request. drift specifications are available on request. 1022fa 3
