7.4.3 Transient Protection

The –16 to 80 V common-mode range of the INA20x devices is ideal for withstanding automotive fault conditions

ranging from 12-V battery reversal up to 80-V transients, since no additional protective components are required

up to those levels. In the event that the INA20x devices are exposed to transients on the inputs in excess of their

ratings, then external transient absorption with semiconductor transient absorbers (such as Zeners) are required.

TI does not recommend using MOVs or VDRs, except when they are used in addition to a semiconductor

transient absorber. Select the transient absorber so the absorber does not allow the INA20x devices to be

exposed to transients greater than 80 V (that is, allow for transient absorber tolerance and additional voltage due

to transient absorber dynamic impedance). Despite the use of internal Zener-type ESD protection, the INA20x

devices do not lend themselves to using external resistors in series with the inputs since the internal gain

resistors can vary up to ±30%. (If gain accuracy is not important, then resistors can be added in series with the

INA200, INA201, and INA202 inputs with two equal resistors on each input.)

7.4.4 Output Voltage Range

The output of the INA20x devices is accurate within the output voltage swing range set by the power supply pin

(VS.) This performance is best illustrated when using the INA202 (a gain of 100 version), where a 100-mV full-

scale input from the shunt resistor requires an output voltage swing of 10 V, and a power-supply voltage

sufficient to achieve 10 V on the output.
