[a] Usage: If “Required” is specified, an electrical connection is necessary; refer to the application circuits in section 3.

Connection: To be connected to this potential if not used or if no application/configuration-related constraints are given.

4.2 ESD Protection

All pins have an ESD protection of > 2000V. Additionally, the pins VDDE, VSSE and AOUT have an ESD protection of >4000V.

ESD protection referenced to the Human Body Model is tested with devices during product qualification. The ESD test follows the Human

Body Model with 1.5kΩ/100pF based on MIL 883, Method 3015.7.
