6 Specifications
6.1 Absolute Maximum Ratings
If military/aerospace specified devices are required, please contact the Texas Instruments sales office, distributors for availability and specifications.(1)(2)| MIN | MAX | UNIT | |
|---|---|---|---|
| VA relative to GND | –0.3 | 6 | V |
| VIO relative to GND | –0.3 | 6 | V |
| Voltage between any two pins(3) | 6 | V | |
| Current in or out of any pin(3) | ±10 | mA | |
| Package input current(3) | ±50 | mA | |
| Power consumption at TA = 25°C | See (4) | ||
| Junction temperature | 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) All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(3) When the input voltage (VIN) at any pin exceeds the power supplies (VIN < GND or VIN > VA), the current at that pin must be limited to 10 mA and VIN must be within the absolute maximum rating for that pin. The 50-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 five.
(4) The absolute maximum junction temperature (TJmax) for this device is 150°C. The maximum allowable power dissipation is dictated by TJmax, the junction-to-ambient thermal resistance (θJA), and the ambient temperature (TA), and can be calculated using the formula PDMAX = (TJmax – TA) / θJA. The values for maximum power dissipation listed above are reached only when the ADC141S628-Q1 is operated in a severe fault condition (for example, when input or output pins are driven beyond the power supply voltages, or the power-supply polarity is reversed). These conditions must be avoided.
6.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per AEC Q100-002(1) | ±4000 | V |
| Charged-device model (CDM), per AEC Q100-011 | ±1250 | |||
| Machine model (MM) | ±300 | |||
(1) AEC Q100-002 indicates that HBM stressing shall be in accordance with the ANSI/ESDA/JEDEC JS-001 specification.
6.3 Recommended Operating Conditions(1)(1)(2)
(1) All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(2) For soldering specifications, see the Absolute Maximum Ratings for Soldering application report.
