6.1.8 Input Protection

The inputs of the INA141 are individually protected for voltages up to ±40 V. For example, a condition of –40 V on one input and +40 V on the other input does not cause damage. Internal circuitry on each input provides low series impedance under normal signal conditions. To provide equivalent protection, series input resistors contributes excessive noise. If the input is overloaded, the protection circuitry limits the input current to a safe value of approximately 1.50 mA to 5 mA. The inputs are protected even if the power supplies are disconnected or turned off.
