6 Specifications

6.1 Absolute Maximum Ratings(1)(2)

MIN MAX UNIT
Supply voltage, VA 6.5 V
Voltage on any input pin −0.3 (VA + 0.3) V
Input current at any pin(3) 10 mA
Maximum output current(4) 10 mA
VOUT pin in power-down mode 1 mA
Package input current(3) 20 mA
Power dissipation at TA = 25°C See(5)
Maximum junction temperature 175 °C
Lead temperature CFP package
(Soldering 10 Seconds)		 260 °C
Package weight (typical) CFP package 220 mg
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 at any pin exceeds the power supplies (that is, less than GND, or greater than VA), 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.
(4) Maximum output current may not exceed 10 mA. At VDD = 5.5 V the minimum external resistive load can be no less than 550 Ω
(360 Ω at VDD = 3.6 V).
(5) The absolute maximum junction temperature (TJmax) for this device is 175°C. 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. The values for maximum power dissipation will be reached only when the device 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). Obviously, such conditions must be avoided.

6.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)(2) ±5000 V
(1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
(2) Human body model is 100-pF capacitor discharged through a 1.5-kΩ resistor. Machine model is 220 pF discharged through 0 Ω.

6.3 Recommended Operating Conditions

MIN MAX UNIT
Operating temperature −55 125 °C
Supply voltage, VA 2.7 5.5 V
Any input voltage(1) −0.1 (VA + 0.1) V
Output load 0 1500 pF
SCLK frequency 20 MHz
(1) The analog inputs are protected as shown below. Input voltage magnitudes up to VA + 300 mV or to 300 mV below GND will not damage this device. However, errors in the conversion result can occur if any input goes above VA or below GND by more than 100 mV. For example, if VA is 2.7-V DC , ensure that –100 mV ≤ input voltages ≤ 2.8-V DC to ensure accurate conversions.
