2.0Description
The PGA309EVM keyhardwareconsistsoftwoboards(see Figure1), PGA309 SensorInterfaceBoardand
PGA309 PCInterfaceBoard.ThePGA309 SensorInterfaceBoardcontainsthe PGA309, externalSOT23-5
EEPROM, and severaljumpersforeaseofbridge sensorconfiguration.The PGA309 PCInterfaceBoard
containsan RS-232 serialinterface, a3V/5Vprogrammablelinearregulator,aswitchforpowercontrol tothe
PGA309 SensorInterfaceBoard, bothOne-Wireand Two-Wireinterfaceconfiguration and controllogic,and
an A/DConverter(ADS1100).
The PGA309EVM isdesigned toallowthe usertoattachhissensortothe PGA309 SensorInterfaceBoard
and placethiscombination inatemperaturechamber. By controlling the applied pressuretothe pressure
sensorand the temperatureofthe temperaturechamber, the PGA309 +Sensorcombinationcan be calibrated
foroptimumend moduleaccuracy.The PGA309 SensorInterfaceBoardisrated foroperation from-40°Cto
+125°C.Power, ground, output and digital interfacewiresconnect the PGA309 SensorInterfaceBoardinthe
temperaturechambertothe external PGA309 PCInterfaceBoard. The PGA309 PCInterfaceBoard
communicatestoatest computerthrough astandardRS-232 serialport via the PGA309EVMPCCable.For
USA shipmentsan ACwalladapterisincluded toprovide 6Vdctothe PGA309 PCInterfaceBoard.Forall
otherapplicationsan alternateconnection on the PGA309 PCInterfaceBoardisprovided forconnection toa
6Vdc(6Vdc-9Vdc) lab supply.The on-boardA/DConverter, ADS1100, on the PGA309 PCInterfaceBoard
allowsforeasyreading of theanalog output ofthe PGA309.
The PGA309EVM Softwareiscomprised of twoparts. The BoardControlSoftwarecontainsallof the interface
and controlforcommunication tothePGA309 through the PGA309 PCInterfaceBoard.It allowsforreading
and writing toallregistersinthePGA309 aswell asreading and writing tothe externalSOT23-5EEPROM.
BothTwo-Wireand One-Wirecommunication optionsareavailable.Inaddition configuration of the PGA309
PCInterfaceBoardand readback of the ADS1100 isprovided.The PGA309 Calibration Spreadsheet for
Microsoft®Excelprovidesauseful tooltocalculateoptimumtemperaturecoefficientsforthe PGA309 +
Sensorcalibration based on real-worldmeasurementsof pressuresat differenttemperatures.The PGA309
Calibration Spreadsheet alsocontainsVisualBasicforApplicationscode that allowsitsintegration withthe
BoardControlSoftware. Thesemacrosallowthe usertoexchange PGA309 settingsbetween the program
and the spreadsheet and savethe resulting EEPROMconfiguration file.

4.4Two-Wire Digital Interface
Two-Wiredigital interfaceisprovided through the conversion of RS-232 signalsfromU9 intoopen drain
outputswithpull-ups(SDAOUT through U6 and SCLOUT through U8). SDAIN istied directtoU9whichislooking
for<0.8Vforalogiclowand >2.0V(3Vsupply) or>2.4V(5Vsupply) foralogichigh. U10 and U11 provide a
mechanism,through softwareorhardware(JE), toseparatethe Two-Wirebusinterfacefromthe PGA309 ifit
isphysicallyconnected.Ifthe PGA309 isinstand-alonemode it will be routinelyaccessing itsexternal

5.1One-Wire Active Pull-Up
The One-WireActivePull-Upcircuitryisintended toprovide afast rising edge pull-upwhen the One-Wire
interfaceisconnected toheavycapacitiveloadssuchaswhen PRG istied toVouton the PGA309 and there
isa10nF capacitoronVouttoGND.Inthisconfiguration thereisan extremelylong risetimedue toa4.7k
pull-up on the One-Wireinterface.One-ShotU14 isrising edge triggered only, non-retriggerable.Comparator
U12 looksforarising edge totransition above0.7V. The One-Shot,U14, then triggersand producesa5μS
wide pulsewhichcontrolsswitchU13.When switchU13isturned on a200 pull-uptoVS isprovided on the
One-WireInterface. Atthe end of the 5μSpulsethe 200 pull-up toVS isremoved. The 5μSwaschosen to
provide anear-symmetricalriseand falltimeintoa10nFload on the One-Wireinterface.RT isaprovisional
potentiometerwhichcan be added tochange the timethe activepull-up isapplied tothe One-WireInterface.

5.2VSQuick Discharge
It isdesired attimestocyclethe poweron the PGA309tobe abletocommunicatethrough PRG,when itis
tied toVout, whileVoutisset tohigh impedancebythePGA309 on initialpower-up. The supplyvoltage on
the PGA309 must decaytonearzerotoensurethat on power-up the stateofthePGA309 isset correctly.
Witha10μF capacitoron Vson the PGA309 PCInterfaceBoardand another10μFcapacitoron Vson the
PGA309 SensorInterfaceBoardreliablereset operationisguaranteed bydischarging thesecapacitors
through U15 and R25. WheneverQ1(see Sheet 1of2–PGA309 PCInterfaceBoardSchematic)isoff and
disconnectspowerfromVsthen U15 ison forquickdischarge of Vs. And wheneverQ1ison then U15 isoff.
