The ADS8481 has a pseudodifferentialunipolar input and the ADS8482 has a pseudo-bipolar, fully differential input. Bothoffer a full 18-bit interface, a 16-bit option where data is read using two read cycles, or an 8-bitbus option using three read cycles. The ADS8472 are 16-bit, 1MSPS versions.+IN–INREFINREFOUTADS8482+4.096-VInternalReferenceADS8482 functional block diagram.CDACSARComparatorClockOutputLatchesand3-StateDriversConversionandControl LogicBYTE16-/8-BITPARALLEL DAOUTPUT BUSBUS 18/16CONVSTBUSYCSRD16-Bit, 500kSPS and 1MSPS, Low Power, Single/Dual Unipolar Input ADCsADS8327, ADS8328, ADS8329, ADS8330Get samples, datasheets, evaluation modules and app reports at: www.ti.com/sc/device/PARTnumber (Replace PARTnumber with ADS8327, ADS8328, ADS8329 or ADS8330)Key Features• Excellent DC performance (ADS8329):• INL: ±1LSB (typ)• DNL: ±0.5LSB (typ)• Excellent AC performance (ADS8329):• SNR: 92dB• SFDR: 102dB• THD: –102dB• Internal conversion clock• Analog supply: 2.7V to 5.5V• SPI/DSP-compatible serial interface• Unipolar input range: 0V to V REF• Multiple power-down modes:Deep, Nap and Autonap• Packaging: TSSOP-16, 4x4 QFNApplications• Communications• Medical instruments• Magnetometers• Industrial process control• ATEThe ADS8327 and ADS8328 (10.6mW at 500kHz) and the ADS8329 and ADS8330 (15.5mW at1MHz) are low-power ADCs with unipolar input and inherent sample and hold. The ADS8328and ADS8330 include a 2:1 input MUX with programmable option of TAG bit output. All offer ahigh-speed, wide voltage serial interface and are capable of chain mode operation whenmultiple converters are used.ADS8328ADS8330+IN1+IN0COMADS8327ADS8329NC+IN–INREF+REF–ADS8328/ADS8330CDACADS8328/ADS8330 functional block diagram.SARComparatorOutputLatch and3-StateDriversOSCConversionCONVERSION&andCONTROLLOGICControl LogicSDOFS/CS–SCLKSDICONVST–EOC/INT–/CDIAmplifier and Data Converter Selection Guide Texas Instruments 3Q 2007
