NOTES
1Adjustable to zero.
2Includes internal voltage reference error.
3Maximum change from 25°C value to the value at TMIN or TMAX.
4Tested with REF OUT tied to REF IN through 50 resistor, VCC = +16.5 V, VEE = –16.5 V, VLOGIC = +5.5 V, and outputs in high-Z mode.
5Tested with REF OUT tied to REF IN through 50 resistor, VCC = +12 V, VEE = –12 V, VLOGIC = +5 V, and outputs in high-Z mode.
Specifications subject to change without notice.
Specifications shown in boldface are tested on all devices at final electrical test at TMIN, 25°C, and TMAX. Results from those tests are used to calculate outgoing quality levels. All min and
max specifications are guaranteed, although only those shown in boldface are tested.
