LMV116/LMV118
Low Voltage, 45MHz, Rail-to-Rail Output Operational
Amplifiers with Shutdown Option
General Description
The LMV116 (single) rail-to-rail output voltage feedback am-
plifiers offer high speed (45MHz), and low voltage operation
(2.7V) in addition to micro-power shutdown capability
(LMV118).
Output voltage range extends to within 20mV of either sup-
ply rail, allowing wide dynamic range especially in low volt-
age applications. Even with low supply current of 600A,
output current capability is kept at a respectable
20mA for
driving heavier loads. Important device parameters such as
BW, Slew Rate and output current are kept relatively inde-
pendent of the operating supply voltage by a combination of
process enhancements and design architecture.
For portable applications, the LMV118 provides shutdown
capability while keeping the turn-off current to l5A. Both
turn-on and turn-off characteristics are well behaved with
minimal output fluctuations during transitions. This allows the
part to be used in power saving mode, as well as multiplex-
ing applications. Miniature packages (SOT23-5 & SOT23-6)
are further means to ease the adoption of these low power
high speed devices in applications where board area is at a
premium.

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.
Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the
maximum allowed junction temperature of 150C.
Note 4: The maximum power dissipation is a function of T
J(MAX)
,
JA
, and T
A
. The maximum allowable power dissipation at any ambient temperature is
P
D
= (T
J(MAX)
- T
A
)/
JA
. All numbers apply for packages soldered directly onto a PC board.
Note 5: Typical values represent the most likely parametric norm.
Note 6: All limits are guaranteed by testing or statistical analysis.
Note 7: Positive current corresponds to current flowing into the device.
Note 8: Slew rate is the average of the rising and falling slew rates.
Note 9: Machine Model, 0
in series with 200pF.
Note 10: Short circuit test is a momentary test. See Note 11.
Note 11: Output short circuit duration is infinite for V
S
<
6V at room temperature and below. For V
S
>
6V, allowable short circuit duration is 1.5ms.
Note 12: Offset voltage average drift determined by dividing the change in V
OS
at temperature extremes into the total temperature change.
Note 13: Guaranteed based on characterization only.
