ST92141 - ELECTRICAL CHARACTERISTICS
8 ELECTRICAL CHARACTERISTICS
This product contains devices to protect the inputs
against damage due to high static voltages, how-
ever it is advisable to take normal precautions to
avoid application of any voltage higher than the
specified maximum rated voltages.
For proper operation it is recommended that VIN
and VO be higher than VSS and lower than VDD.
Reliability is enhanced if unused inputs are con-
nected to an appropriate logic voltage level (VDD
or VSS).
Power Considerations. The average chip-junc-
tion temperature, TJ, in Celsius can be obtained
from:
TJ =TA +PD x RthJA
Where: TA =
Ambient Temperature.
RthJA = Package thermal resistance
(junction-to ambient).
PD =PINT +PPORT.
PINT =IDD xVDD (chip internal power).
PPORT =Port power dissipation
(determined by the user)
ABSOLUTE MAXIMUM RATINGS
Note:
Stresses above those listed as “absolute maximum ratings“ may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect
device reliabili ty. All voltages are referenced to VSS=0.
(1) AVDD can be shut down while the A/D Converter is not in use.
THERMAL CHARACTERISTICS
RECOMMENDED OPERATING CONDITIONS
Note:
(1) Device is reset whenever Supply Voltage is below LVD Thresholds
(2) 1MHz when A/D is used with its internal Prescaler programmed to 1.
