These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) DBT packaged versions of ADS79xx family devices are rated for MSL2 260°C per the JSTD-020 specifications and the RGE and RHB packaged versions of ADS79xx family devices are rated for MSL3 260C per JSTD-020 specifications 7.2 ESD Ratings VALUE UNIT Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22- ±500 C101(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. 7.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT V(+VA) Analog power-supply voltage 2.7 3.3 5.25 V V(+VBD) Digital I/O-supply voltage 1.7 3.3 V(+VA) V V(REF) Reference voltage 2 2.5 3 V ƒ(SCLK) SCLK frequency 20 MHz TA Operating temperature range –40 125 °C 8 Submit Documentation Feedback Copyright © 2008–2015, Texas Instruments Incorporated Product Folder Links: ADS7950 ADS7951 ADS7952 ADS7953 ADS7954 ADS7955 ADS7956 ADS7957 ADS7958 ADS7959 ADS7960 ADS7961 |
