3 / 10 page Production Data WM2639 WOLFSON MICROELECTRONICS LTD Production Data Rev 1.0 July 1999 3 ABSOLUTE MAXIMUM RATINGS Absolute Maximum Ratings are stress ratings only. Permanent damage to the device may be caused by continuously operating at or beyond these limits. Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test conditions specified ESD Sensitive Device. This device is manufactured on a CMOS process. It is therefore generically susceptible to damage from excessive static voltages. Proper ESD precautions must be taken during handling and storage of this device. CONDITION MIN MAX Digital supply voltages, VDD to GND 7V Reference input voltage -0.3V VDD + 0.3V Digital input voltage range to GND -0.3V VDD + 0.3V Operating temperature range, TA WM2639CDT WM2639IDT 0 °C -40 °C 70 °C 85 °C Storage temperature -65 °C 150 °C Lead temperature 1.6mm (1/16 inch) soldering for 10 seconds 260 °C RECOMMENDED OPERATING CONDITIONS PARAMETER SYMBOL TEST CONDITIONS MIN TYP MAX UNIT Supply voltage VDD 2.7 5.5 V High-level digital input voltage VIH VDD = 2.7V to 5.5V 2 V Low-level digital input voltage VIL VDD = 2.7V to 5.5V 0.8 V Reference voltage to REF VREF See Note VDD - 1.5 V Load resistance RL 2 k Ω Load capacitance CL 100 pF WM2639CDT 0 70 °C Operating free-air temperature TA WM2639IDT -40 85 °C Note: Reference voltages greater than VDD/2 will cause output saturation for large DAC codes. |
