Transient Protection

The –16 V to 80 V common-mode range of the INA203, INA204, and INA205 is ideal for withstanding automotive fault conditions ranging from 12-V battery reversal up to 80-V transients, since no additional protective components are needed up to those levels. In the event that the INA203, INA204, and INA205 are exposed to transients on the inputs in excess of their ratings, then external transient absorption with semiconductor transient absorbers (Zeners or Transzorbs) are necessary. Use of metal oxide varistors (MOVs) or video disk recorders (VDRs) is not recommended except when they are used in addition to a semiconductor transient absorber. Select the transient absorber such that it will never allow the INA203, INA204, and INA205 to be exposed to transients greater than 80 V (that is, allow for transient absorber tolerance, as well as additional voltage because of transient absorber dynamic impedance). Despite the use of internal Zener-type ESD protection, the INA203, INA204, and INA205 do not lend themselves to using external resistors in series with the inputs because the internal gain resistors can vary up to ±30% but are closely matched. (If gain accuracy is not important, then resistors can be added in series with the INA203, INA204, and INA205 inputs with two equal resistors on each input.)
