SBAU383A June 2021 – February 2022 BUF802
The BUF802RGTEVM composite loop circuit also includes footprints for optional clamping diodes D1 and D2. These diodes are attached to the CLH and CLL pins, which are then connected to the supplies through series resistors R1 and R2 respectively. These diodes can be populated in cases where the 100 mA current rating of the internal diode clamps is insufficient. When using external clamping, disable the BUF802's internal protection by connecting CLH and CLL to the positive and negative supply respectively.
