Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product

performance may not be indicated by the Electrical Characteristics if operated under different conditions.

3. Vcc detection for BS_OK must trip in this range. Device can be either operational or not operational in this range.

4. Shunt Monitor Offset Voltage and Offset Voltage Drift are referred to the SH_IN_Px and SH_IN_Nx pins.

6. Differential Amplifier Offset Voltage and Offset Voltage Drift are referred to the multiplexer input pins (e.g. BS_INx or SH_Ox).
