Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress Parameter Rating rating only; functional operation of the device at these or any VDD to GND −0.3 V to +7 V other conditions above those indicated in the operational DIN Input Voltage to GND −0.3 V to VDD + 0.3 V section of this specification is not implied. Exposure to absolute DOUT Voltage to GND −0.3 V to VDD + 0.3 V maximum rating conditions for extended periods may affect SCLK Input Voltage to GND −0.3 V to VDD + 0.3 V device reliability. CS Input Voltage to GND −0.3 V to VDD + 0.3 V CT and INT Output Voltage to GND −0.3 V to VDD + 0.3 V ESD CAUTION ESD Rating (Human Body Model) 2.0 kV Operating Temperature Range1 −40°C to +150°C Storage Temperature Range −65°C to +160°C Maximum Junction Temperature, TJMAX 150°C Power Dissipation2 16-Lead LFCSP3 WMAX = (TJMAX − TA)/θJA Thermal Impedance4 θ JA, Junction-to-Ambient (Still Air) 37°C/W θJC, Junction-to-Case 33°C/W IR Reflow Soldering 220°C Peak Temperature (RoHS-Compliant 260°C (0°C/−5°C) Package) Time at Peak Temperature 20 sec to 40 sec Ramp-Up Rate 3°C/sec maximum Ramp-Down Rate −6°C/sec maximum Time from 25°C to Peak Temperature 8 minutes maximum 1 Sustained operation above 125°C results in a shorter product lifetime. For more information, contact an Analog Devices, Inc., sales representative. 2 Values relate to package being used on a standard 2-layer PCB. This gives a worst-case θJA and θJC. 3 TA = ambient temperature. 4 Junction-to-case resistance is applicable to components featuring a preferential flow direction, for example, components mounted on a heat sink. Junction-to-ambient resistance is more useful for air cooled, PCB- mounted components.
