OPA0 Functions

TheOPA0canoperatetogetherwiththeMUX,DACandOPA1asshowninthemainfunctional

blocksoftheBatterychargingcircuit.

TheOPA0providesitsinputvoltageoffsettobeadjustablebyusingcommonmodeinputto

calibratetheoffset.

Thecalibrationstepsareasfollowing:

• 1.SetA0FM=1tosetuptheoffsetcalibrationmode,hereS1onandS2off.

• 2.SetA0RSPtoselectwhichinputpinistobeusedasthereferencevoltage–IsensepinorVM.

• 3.AdjustA0OF4~A0OF0untiltheoutputstatuschanges

• 4.SetA0FM=0torestorethenormalmode.

Note:1.Whencalibration,thedevicecandetecttheOPAoutputstatusbyA0Xbit.

2.VMvoltageis0.1VatVDD=5V.

3.AfterOPA0offsetcalibration,settheA0RSPbitbytheactualapplications.
