A typical operation for the TVS1401 would be protecting in a factory control application and protecting an analog input to an ADC input similar to Figure 10-1. In this example, the TVS1401 is protecting the input to an ADS8689, an ADC with an input voltage range of ±12.288 V and an absolute maximum input voltage range of ±20 V. Without any input protection, this input voltage will rise to hundreds of volts for multiple microseconds, and violate the absolute maximum input voltage and harm the device if a surge event is caused by lightning, coupling, ringing, or any other fault condition. TI's Flat-Clamp technology provides surge protection diodes that can maximize the useable voltage range at a safe level for the system.
