Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified
Note 2:
The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.
Note 3:
The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX, θJA, and the ambient temperature, TA. The maximum
allowable power dissipation is P
DMAX = (TJMAX - TA) / θJA or the number given in Absolute Maximum Ratings, whichever is lower.
Note 4:
Human body model, applicable std. JESD22-A114C.
Note 5:
Machine model, applicable std. JESD22-A115-A.
Note 6:
Typical values represent most likely parametric norms at T
A = +25C, and at the Recommended Operation Conditions at the time of product
characterization and are not guaranteed.
Note 7:
Datasheet min/max specification limits are guaranteed by test or statistical analysis.
Note 8:
The maximum operating junction temperature is 150°C.
Note 9:
The Data taken with Bandwidth = 30kHz, A
V = 29dB, CC = 30pF, and TA = 25°C except where specified.
