The voltage slew rate of certain high-voltage terminals of TPA3111D1 must be restricted to no more than 10 V/ms. These terminals include SDZ， GAIN0， GAIN1， FAULT， and terminal 14. When these terminals are directly tied to the supply， the ESD cells can be triggered when the slew rate is more than 10 V/ms. For higher slew rates， use a 100-kΩ resistor in series with the terminals.
Figure 1 shows a typical application circuit containing the TPA3111D1 in BTL configuration. The 100-kΩ series resistor on terminal 14 prevents triggering the ESD cell when the slew rate of AVCC is more than 10 V/ms. For more information on the TPA3111D1， see to the product data sheet （SLOS618）。
