These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: All voltages are with respect to GND. Recommended Operating Conditions MIN NOM MAX UNIT Supply voltage, VDD 2.6 3 3.6 V Supply voltage accuracy, VDD total error including transients −3 3 % Operating free-air temperature, TA (Note 2) −30 85 °C NOTE 2: While the device is operational across the temperature range, functionality will vary with temperature. Specifications are stated only at 25 °C unless otherwise noted. |
