LMV841 Single / LMV844 Quad CMOS Input, RRIO, Wide Supply Range Operational Amplifiers
March 2007
General Description
The LMV841 and LMV844 are low-voltage and low-power
operational amplifiers that operate with supply voltages ranging from 2.7V to 12V and have rail-to-rail input and output
capability.
The LMV841 and LMV844 are low offset voltage and low
supply current amplifiers with MOS inputs, characteristics that
make the LMV841/LMV844 ideal for sensor interface and
battery powered applications.
The LMV841 is offered in the space saving 5-pin SC70 package and the quad LMV844 comes in the 14-Pin TSSOP
package. These small packages are solutions for area constrained PC boards and portable electronics.

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, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std. JESD22-A115-A (ESD MM std. of JEDEC) FieldInduced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC).
Note 3: The maximum power dissipation is a function of T
PD = (T
Note 4: 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 5: Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will
also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material.
Note 6: Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlations using statistical quality
control (SQC) method.
Note 7: This parameter is guaranteed by design and/or characterization and is not tested in production.
Note 8: Positive current corresponds to current flowing into the device.
Note 9: Short circuit test is a momentary test.
Note 10: Number specified is the slower of positive and negative slew rates.
