LPV511
880 nA, Rail-to-Rail Input and Output Operational
Amplifier
General Description
The LPV511 is a micropower operational amplifier that op-
erates from a voltage supply range as wide as 2.7V to 12V
with guaranteed specifications at 3V, 5V and 12V. The
LPV511 exhibits an excellent speed to power ratio, drawing
only 880 nA of supply current with a bandwidth of 27 kHz.
These specifications make the LPV511 an ideal choice for
battery powered systems that require long life through low
supply current, such as instrumentation, sensor conditioning
and battery current monitoring.
The LPV511 has an input range that includes both supply
rails for ground and high side battery sensing applications.
The LPV511 output swings within 100 mV of either rail to
maximize the signal's dynamic range in low supply applica-
tions. In addition, the output is capable of sourcing 650 µA of
current when powered by a 12V battery.
The LPV511 is available in the space saving SC70 package
which makes it ideal for portable electronics with area con-
strained PC boards.

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 Tables.
Note 2: Human Body Model: 1.5 k
in series with 100 pF. Machine Model: 0 in series with 200 pF.
Note 3: 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 4: Output short circuit duration is infinite for V
+
<
6V at room temperature and below. For V
+
>
6V, allowable short circuit duration is 1.5 ms.
Note 5: 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.
Note 6: Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlations using the Statistical Quality
Control (SQC) method.
Note 7: Typical values represent the most likely parametric norm at the time of characterization.
Note 8: Offset voltage average drift is determined by dividing the change in V
OS
at temperature extremes into the total temperature change.
Note 9: Positive current corresponds to current flowing into the device.
Note 10: The Short Circuit Test is a momentary test. See (Note 4).
Note 11: Slew rate is the average of the rising and falling slew rates.
