NOTES
1Temperature ranges are as follows: J Grade: 0°C to +70°C, S Grade: –55°C to +125°C.
2Adjustable to zero with external potentiometers (see Zero and Gain Error Calibration section).
3+25°C to TMIN and +25°C to TMAX.
4Includes internal voltage reference error.
5Excludes internal reference drift.
6Change in Gain Error as a function of the dc supply voltage (VNOMINAL to VMIN, VNOMINAL to VMAX).
7LCC package only.
Specifications subject to change without notice.
