The analog inputs – SNR: are maintained differentially to the input of the ADC. 93dB(ADS8363) The input multiplexer can be used in either pseudo- differential mode, supporting up to four channels per 85dB(ADS7263) ADC (4x2), or in fully-differential mode that allows to 73dB(ADS7223) convert up to two inputs per ADC (2x2). The – THD: ADS7263 is a 14-bit version and the ADS7223 is a –98dB(ADS8363) 12-bitversionoftheADS8363. –92dB(ADS7263) The ADS8363, ADS7263, and ADS7223 offer two –86dB(ADS7223) programmable reference outputs, flexible supply • DualProgrammableandBuffered2.5-V voltage ranges, a programmable auto-sequencer, ReferenceAllows: data storage of up to four conversion results per – TwoDifferentInputVoltageRangeSettings channel, andseveralpower-downfeatures. – Two-LevelPGAImplementation All devices are offered in a 5-mm x 5-mm, 32-pin • ProgrammableAuto-Sequencer VQFNpackage. • IntegratedDataStorage(upto4perchannel)for DeviceInformation(1) Oversampling Applications PARTNUMBER PACKAGE BODYSIZE(NOM) • 2-BitCounterforSafetyApplications ADSxxx3 VQFN(32) 5.00mmx5.00mm • FullySpecifiedOvertheExtendedIndustrial (1) Forallavailablepackages,seethepackageoptionaddendum TemperatureRange:–40°Cto+125°C attheendofthedatasheet. 2 Applications FunctionalBlockDiagram • MotorControl:CurrentandPositionMeasurement AVDD DVDD includingSafetyApplications • PowerQualityMeasurement CHA1P/CHA3 • Three-PhasePowerControl CHA1N/CHA2 Input CHA0P/CHA1 SAR ADC CS • ProgrammableLogicControllers CHA0N/CHA0 Mux CLOCK • IndustrialAutomation CMA REF1 InSteerrfiaacle BUSY SDI • ProtectionRelays REF2 and CHB1P/CHB3 FIFO RD CHB1N/CHB2 SDOA Input CHB0P/CHB1 SAR ADC SDOB Mux CHB0N/CHB0 CMB REF1 M0 String 2.5V Control REFIO1 M1 DAC REF Logic REF2 CONVST String REFIO2 DAC RGND AGND DGND 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectualpropertymattersandotherimportantdisclaimers.PRODUCTIONDATA.
