7.5 Input and ESD Protection

The TLV600x-Q1 family incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case of input and output pins, this protection primarily consists of current-steering diodes connected between the input and power supply pins. The ESD protection diodes provide in-circuit, input overdrive protection if the current is limited to 10 mA, as the Absolute Maximum Ratings lists. Figure 20 shows how a series input resistor can be added to the driven input to limit the input current. The added resistor contributes thermal noise at the amplifier input and the value must be kept to a minimum in noise-sensitive applications.
