7.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)(2)(3)| MIN | MAX | UNIT | ||
|---|---|---|---|---|
| Supply voltage, VA | 6.5 | V | ||
| Voltage on any input pin | –0.3 | 6.5 | V | |
| Input current at any pin(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) All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications.
(4) When the input voltage at any pin exceeds 5.5 V or is less than GND, the current at that pin must 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 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 is reached only when the device is operated in a severe fault condition (that is, when input or output pins are driven beyond the operating ratings, or the power supply polarity is reversed).
7.2 ESD Ratings
| VALUE | UNIT | |||
|---|---|---|---|---|
| V(ESD) | Electrostatic discharge | Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) | ±2500 | V |
| Machine model (MM) | ±250 | |||
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
7.3 Recommended Operating Conditions
over operating free-air temperature range (unless otherwise noted)(1)| MIN | NOM | MAX | UNIT | ||
|---|---|---|---|---|---|
| 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 | |||
| TA | Operating temperature | –40 | 105 | °C | |
(1) All voltages are measured with respect to GND = 0 V, unless otherwise specified.
(2) The inputs are protected as shown below. 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.
7.4 Thermal Information
| THERMAL METRIC(1) | DAC124S085 | UNIT | ||
