Notes
* 3. VCM means the common voltage of an input pin (PIN/NIN).
* 4. VIOD = [( high temperature side WST(**)) –( low temperature side WST(**))]/[125°C－(－40°C)）]
** WST is MIN. or MAX. value of VIO.
ex.) If high temperature side is MAX. and low temperature side is MIN. the VIOD polarity is
positive. And if high temperature side is MIN. and low temperature side is MAX. the VIOD
polarity is negative.
* 5. CMRR = 20 x Log[(VDD-VSS) / ( α )]
‘( α ) is a Max. value among [(Offset at input = VDD)-(Offset at Input = VSS)] and
[(Offset at input = VDD)-( Offset at input = VDD/2)] and
[(Offset at input = VDD/2)-( Offset at input = VSS)].
* 6. PSRR = 20 x Log[(Max. supply voltage – Min. supply voltage) / (Offset at Max. supply voltage –
Offset at Min. supply voltage)]
* 7. AV = 20×LOG [ ((VDD-0.2)－(VSS+0.2)) /
((Offset at output= VDD－0.2) － (Offset at output = VSS+0.2)）]
* 8. It contains consumption of one OPAmp circuit. It doesn't include an output drive current.
