7.1
Absolute Maximum Ratings*
Supply Voltage ................................................................................................................... +3.3V +/- 10%
Operating Temperature .............................................................................................................. 0 to 70°C
Storage Temperature.........................................................................................................-65°C to 150°C
Positive Voltage on any pin, with respect to Ground ........................................................................ 5.5V
Negative Voltage on any pin, with respect to Ground ..................................................................... -0.3V
Note: The maximum pin ratings do not apply to the following analog pins - ATEST, RBIAS, EXRES1,
TPO +/-, TPI +/-
* Stresses exceeding those listed above could cause permanent damage to the device. This is a stress
rating only and functional operation of the device at any other condition above those indicated in the
operation sections of this specification is not implied.
Note:
When powering this device from laboratory or system power supplies, it is important that the
absolute maximum ratings not be exceeded or device failure can result. Some power supplies
exhibit voltage spikes on their outputs when AC power is switched on or off. In addition, voltage
transients on the AC power line may appear on the DC output. If this possibility exists, it is
suggested that a clamp circuit be used.
7.2
