Note:

1) Common mode pressure is defined as the maximum pressure that can be applied simultaneously on both pressure

ports of a differential or bidirectional transmitter without causing damages while no further differential pressure is ap-

plied.

SPECIFICATIONS

All parameters apply to Top = 25 °C and VS = 3.3 V (3.3 V models) or VS = 5.0 V (5 V models), unless otherwise stated.
