(2) The deviation parameters VREF(dev) and Iref(dev) are defined as the differences between the maximum and minimum values obtained over the rated temperature range. The average full-range temperature coefficient of the reference input voltage, αVREF, is defined as: where ΔTA is the rated operating free-air temperature range of the device. αVREF can be positive or negative, depending on whether minimum VREF or maximum VREF, respectively, occurs at the lower temperature. spacer When the device is operating with two external resistors (see Figure 20), the total dynamic impedance of the circuit is defined as: 6 Submit Documentation Feedback Copyright © 1996–2015, Texas Instruments Incorporated Product Folder Links: TLV431 TLV431A TLV431B |
