2.5V Max VCM + 0.5V VCM VCM - 0.5V 0V Min 2.5V Max VCM + 1V VCM VCM - 1V 0V Min ADC10065 www.ti.com SNAS225H –JULY 2003–REVISED APRIL 2013 FUNCTIONAL DESCRIPTION The ADC10065 uses a pipelinearchitectureand has errorcorrectioncircuitryto help ensure maximum performance.Differentialanaloginputsignalsare digitizedto 10 bits.In differentialmode, each analoginput signalshouldhave a peak-to-peakvoltageequalto1.0V,0.75V or 0.5V,dependingon thestateoftheIRS pin (pin5),and be centeredaround VCM and be 180° out of phase witheach other.Ifsingleended operationis desired,VIN-may be tiedtotheVCOM pin(pin4).A singleended inputsignalmay thenbe appliedtoVIN+,and shouldhave an averagevalueintherangeofVCM .The signalamplitudeshouldbe 2.0V,1.5V or1.0V peak-to- peak,dependingon thestateortheIRS pin(pin5). ApplicationsInformation ANALOG INPUTS The ADC10065 has two analogsignalinputs,VIN+ and VIN−.These two pinsforma differentialinputpair.There isone common mode pinVCOM thatmay be used tosetthecommon mode inputvoltage. REFERENCE PINS The ADC10065 isdesignedto operatewitha 1.2V reference.The voltagesat VCOM , VREFT , and VREFB are derivedfromthereferencevoltage.Itisveryimportantthatallgroundsassociatedwiththereferencevoltageand theinputsignalmake connectiontotheanalogground planeata singlepointtominimizetheeffectsofnoise currentsintheground path.The threeReferenceBypass PinsVREF ,VREFT and VREFB ,are made availablefor bypass purposesonly.These pinsshouldeach be bypassed togroundwitha 0.1µF capacitor.DO NOT LOAD thesepins. VCOM PIN This pin suppliesa voltageforpossibleuse to set the common mode inputvoltage.This pin may alsobe connectedtoVIN-,so thatVIN+ may be used as a singleended input.Thispinshouldbe bypassed withatleasta 0.1µF capacitor.Do notloadthispin. SIGNAL INPUTS The signalinputsare VIN+ and VIN−. The inputsignalamplitudeisdefinedas VIN+ − VIN− and isrepresented schematicallyinFigure40: Figure40.InputVoltageWaveforms fora 2VP-P Figure41.InputVoltageWaveform fora 2VP-P differentialInput SingleEnded Input A singleended inputsignalisshown inFigure41. The internalswitchingactionattheanaloginputscauses energytobe outputfromtheinputpins.As thedriving sourcetriestocompensate forthis,itadds noisetothesignal.To preventthis,use 18Ω seriesresistorsateach of the signalinputpinswitha 25 pF capacitoracrossthe inputs,as shown inFigure42. These components shouldbe placedclosetotheADC because theinputpinsoftheADC isthemost sensitivepartofthesystem and thisisthelastopportunitytofiltertheinput.The two 18Ω resistorsand the25 pF capacitorforma low-pass filterwitha -3dB frequencyof177 MHz.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
