LMV721/LMV722
10MHz, Low Noise, Low Voltage, and Low Power
Operational Amplifier
General Description
The LMV721 (Single) and LMV722 (Dual) are low noise, low
voltage, and low power op amps, that can be designed into
a wide range of applications. The LMV721/LMV722 has a
unity gain bandwidth of 10MHz, a slew rate of 5V/us, and a
quiescent current of 930uA/amplifier at 2.2V.
The LMV721/722 are designed to provide optimal perfor-
mance in low voltage and low noise systems. They provide
rail-to-rail output swing into heavy loads. The input
common-mode voltage range includes ground, and the
maximum input offset voltage are 3.5mV (Over Temp.) for
the LMV721/LMV722. Their capacitive load capability is also
good at low supply voltages. The operating range is from
2.2V to 5.5V.
The chip is built with National's advanced Submicron
Silicon-Gate BiCMOS process. The single version, LMV721,
is available in 5 pin SOT23-5 and a SC-70 (new) package.
The dual version, LMV722, is available in a SO-8 and
MSOP-8 package.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended 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, 1.5 k
in series with 100 pF. Machine model, 200
in series with 100 pF.
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. Output currents in excess of 30 mA over long term may adversely affect reliability.
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 into 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: Connected as voltage follower with 1V step input. Number specified is the slower of the positive and negative slew rate.
