The TLV380x-Q1 features an input stage, capable of operating between 1.5 V above VEE and 0.1 V above VCC, with an internal ESD protection circuit that includes two pairs of front-to-back diodes between IN+ and IN- as well as two 50 Ω resistors, as shown in Figure 7-1. This prevents damage to the input stage by limiting the differential input voltage to be no more than twice the diode's forward-voltage drop 2 × V_F (2 × 0.7 V).

When the differential input voltage exceeds 2 × V_F, the input bias current increases at the input pins IN+ and IN-, as shown in Equation 5.

To avoid damaging the inputs when exceeding the recommended input voltage range, an external resistor should be used to limit the current. The current should be limited to less than 10 mA.
