(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not specific performance limits. For specifications and test conditions, see the
Electrical Characteristics.
(2) The maximum allowable power dissipation is a function of the maximum junction temperature, T
J_MAX
, the junctions-to-ambient thermal
resistance, θ
JA
, and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperature is calculated
using: P
D_MAX
= (T
J_MAX
– T
A
)/θ
JA
. The maximum power dissipations of 2.6W is determined using T
A
= 25°C, θ
JA
= 38°C/W, and T
J_MAX
= 125°C.
(3) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor to each pin.
OPERATING RATINGS
PVIN, AVIN to GND 2.95V to 5.5V
Junction Temperature −40°C to + 125°C
