See Offset/Gain Calibration section for additional information. 2Full-scale range (FSR) is 5 V for the 0 V to 5 V range and 10 V for the 0 V to 10 V and –5 V to +5 V ranges. 325 °C to T MIN and 25°C to TMAX. 4Change in gain error as a function of the dc supply voltage. 5Tested under static conditions. See Figure 12 for typical curves of I LOGIC vs. Conversion Rate and Output Loading. Specifications subject to change without notice. Specifications shown in boldface are tested on all devices at final electrical test with worst case supply voltages at 0, +25 °C and +70°C. 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. REV. B –2– |
