10.1.4 Input Protection

The ADS111xL are fabricated in a small-geometry, low-voltage process. The analog inputs feature protection diodes to the supply rails. However, the current-handling ability of these diodes is limited, and the ADS111xL can be permanently damaged by analog input voltages that exceed approximately 300 mV beyond the rails for extended periods. One way to protect against overvoltage is to place current-limiting resistors on the input lines. The ADS111xL analog inputs can withstand continuous currents as large as 10 mA.
