Note 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 specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2:
Human body model, 1.5k
in series with 100pF. Machine model, 0
in series with 20pF.
Note 3:
Shorting output to V

will adversely affect reliability.
Note 4:
Shorting output to V

Note 5:
The maximum power dissipation is a function of T

Note 6:
Typical Values represent the most likely parametric norm.
Note 7:
All limits are guaranteed by testing or statistical analysis.
Note 8:
Limits guaranteed by design.

Note 10:
For LMV772/LMV774, temperature limits apply to 40C to 85C.
Note 11:
For LMV772/LMV774, temperature limits apply to 40C to 85C. If R
L
is relaxed to 10k
, then for LMV772/LMV774 temperature limits apply to 40C to
125C.
Note 12:
Connected as voltage follower with 2V
PP
step input. Number specified is the slower of positive and negative slew rates.
Note 13:
Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating
of the device such that T
J
= T
A
. No guarantee of parametric performance is indicated in the electrical tables under the conditions of internal self-heating where T
J
>
T
A
. Absolute Maximum Rating indicated junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically.
Note 14:
Continuous operation of the device with an output short circuit current larger than 35mA may cause permanent damage to the device.
