LMV831 Single/ LMV832 Dual/ LMV834 Quad
3.3 MHz Low Power CMOS, EMI Hardened Operational
Amplifiers
General Description
National’s LMV831, LMV832, and LMV834 are CMOS input,
low power op amp IC's, providing a low input bias current, a
wide temperature range of −40°C to 125°C and exceptional
performance making them robust general purpose parts. Ad-
ditionally, the LMV831/LMV832/LMV834 are EMI hardened
to minimize any interference so they are ideal for EMI sensi-
tive applications.
The unity gain stable LMV831/LMV832/LMV834 feature
3.3 MHz of bandwidth while consuming only 0.24 mA of cur-
rent per channel. These parts also maintain stability for ca-
pacitive loads as large as 200 pF. The LMV831/LMV832/
LMV834 provide superior performance and economy in terms
of power and space usage.
This family of parts has a maximum input offset voltage of
1 mV, a rail-to-rail output stage and an input common-mode
voltage range that includes ground. Over an operating range
from 2.7V to 5.5V the LMV831/LMV832/LMV834 provide a
PSRR of 93 dB, and a CMRR of 91 dB. The LMV831 is offered
in the space saving 5-Pin SC70 package, the LMV832 in the
8-Pin MSOP and the LMV834 is offered in the 14-Pin TSSOP
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
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) Field-
Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC).
Note 3: The maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is
PD = (TJ(MAX) - TA)/ θJA . All numbers apply for packages soldered directly onto a PC board.
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 such that TJ = TA. No guarantee of parametric performance is indicated in the electrical tables under conditions of internal self-heating where
TJ > TA.
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: Number specified is the slower of positive and negative slew rates.
Note 8: The EMI Rejection Ratio is defined as EMIRR = 20log ( VRF_PEAK/ΔVOS).
Note 9: The typical value is calculated by applying absolute value transform to the distribution, then taking the statistical average of the resulting distribution.
Note 10: This parameter is guaranteed by design and/or characterization and is not tested in production.
Note 11: The specified limits represent the lower of the measured values for each output range condition.
