1) Pre-configured setting, for other pre-configured versions please contact your local sales.

2) Can be programmed by user (valid only for 120A version).

3) Values refer to semi-differential mode or single-ended mode, with VREF =1.65 V.

In fully-differential mode the sensitivity value is doubled.

4) Not subject to production test. Verified by design and characterization.

5) Typical value in fully-differential mode, sensitivity range S6
