The data sheet page 1 states: " The fully differential X, Y, and Z input interfaces are operational over a ±2 V range operation".  This a swing of 4 V p-p.

The detailed specs on page 3  show:  Differential Voltage Range, Differential, common mode = 2.5, 2 V p-p.

Which is correct?

I assume that 2 V p-p means +1V to -1V on the differential inputs,  +1V differential = 3.5V on V+ and -2.5V on V-  (with 2.5 V common mode)

• Typo in last line, meant to say:  I assume that 2 V p-p means +1V to -1V on the differential inputs,  +1V differential = 3.5V on V+ and +2.5V on V-

• Bad math day yesterday..  +1  differential = +3.0V on V+ and +2.0V on V- for +2.5V common mode.

• Hello,

The spec isn't +/- 2V per pin, but rather +/-2V (differential) per interface.  Figure 3 really tells the tale here. The specs table, as you mention, is correct.  2Vpp differential w/ a 2.5V common-mode, means one pin is going to +3.5V while the other is going to +1.5V.

Thanks,

Darrell

• My point is that if the differential voltage can be +2V to -2V, that is a total swing of 4V (or 4V peak to peak NOT 2Vpp)
