7.1 Absolute Maximum Ratings

See (1)(2)(3)
MIN MAX UNIT
Supply voltage VA 6.5 V
Voltage DIN, SCLK, SYNC, VREFIN −0.3 6.5 V
Input current(4) 10 mA
Package input current(4) 20 mA
Power consumption at TA = 25°C See(5)
Junction temperature, TJ 150 °C
Storage temperature, Tstg −65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications.
(3) All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(4) When the input voltage at any pin exceeds 5.5 V or is less than GND, the current at that pin should be limited to 10 mA. The 20-mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of
10 mA to two.
(5) The maximum allowable power dissipation is dictated by TJmax, the junction-to-ambient thermal resistance (RθJA), and the ambient temperature (TA), and can be calculated using the formula PDmax = (TJmax - TA) / RθJA.

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2500 V
Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±250
(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

See (1)
MIN MAX UNIT
Operating temperature –40 105 °C
VA Supply voltage 2.7 5.5 V
VREFIN Reference voltage 1 VA V
Digital input voltage(2) 0 5.5 V
Output load 0 1500 pF
SCLK frequency 40 MHz
(1) All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(2) The inputs are protected. Input voltage magnitudes up to 5.5 V, regardless of VA, do not cause errors in the conversion result. For example, if VA is 3 V, the digital input pins can be driven with a 5-V logic device.
