Note 1: Absolute Maximum Ratings are those values beyond which the
life of a device may be impaired.
Note 2: Offset voltage is measured under two different conditions:
(a) approximately 0.5 seconds after application of power;
(b) at TA = 25°C, with the chip self-heated to approximately 45°C
to account for chip temperature rise when the device is fully warmed up.
Note 3: 10Hz noise voltage density is sample tested on every lot of A
grades. Devices 100% tested at 10Hz are available on request.
Note 4: This parameter is tested on a sample basis only.
Note 5: Current noise is calculated from the formula: in = (2qIB)1/2, where
q = 1.6 10 –19 coulomb. The noise of source resistors up to 1G swamps
the contribution of current noise.
Note 6: Offset voltage drift with temperature is practically unchanged when
the offset voltage is trimmed to zero with a 100k potentiometer between
the balance terminals and the wiper tied to V +. Devices tested to tighter
drift specifications are available on request.
The ● denotes the specifications which apply over the full operating temperature range of – 55°C ≤ TA ≤ 125°C. VS = ±15V, VCM = 0V,
unless otherwise noted.
