Input Protection

The inputs of the INA114 are individually protected for voltages up to ±40V. For example, a condition of –40V on one input and +40V 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 contribute excessive noise. If the input is overloaded, the protection circuitry limits the input current to a safe value (approximately 1.5mA). Typical performance curve Input Bias Current vs Common-Mode Input Voltage shows this input current limit behavior. The inputs are protected even if no power supply voltage is present.
