Input current protection circuit constituted by the INA155/156 circuit as shown: As shown by INA155/156 constitute input current protection circuit. INA155 inputs have internal electrostatic discharge (ESD) protection diodes, when the input voltage exceeds the supply voltage of 500mV, protection diodes will turn on, then RLIM will limit the input current (maximum 10mA), play a role in the protection circuit. Many of the input signal itself is limited streaming capabilities, which limit the flow resistance RLIM can not.
