2 / 51 page ADS8528 ADS8548 ADS8568 SBAS543A – AUGUST 2011 – REVISED OCTOBER 2011 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. FAMILY/ORDERING INFORMATION(1) MAXIMUM DATA RATE: RESOLUTION PAR/SER SNR THD PRODUCT (Bits) (kSPS/ch) (dB, typ) (dB, typ) ADS8528 12 650/480 73.9 –89 ADS8548 14 600/450 85 –91 ADS8568 16 510/400 91.5 –94 (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or visit the device product folder at www.ti.com. ABSOLUTE MAXIMUM RATINGS (1) Over operating free-air temperature range, unless otherwise noted. VALUE UNIT HVDD to AGND –0.3 to 18 V HVSS to AGND –18 to 0.3 V Supply voltage AVDD to AGND –0.3 to 6 V DVDD to DGND –0.3 to 6 V Analog input voltage HVSS – 0.3 to HVDD + 0.3 V Reference input voltage with respect to AGND AGND – 0.3 to AVDD + 0.3 V Digital input voltage with respect to DGND DGND – 0.3 to DVDD + 0.3 V Ground voltage difference AGND to DGND ±0.3 V Input current to all pins except supply ±10 mA Maximum virtual junction temperature, TJ +150 °C Human body model (HBM) ±2500 V JEDEC standard 22, test method A114-C.01, all pins ESD ratings Charged device model (CDM) ±500 V JEDEC standard 22, test method C101, all pins (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
