Single, Dual, and Quad 40V Low Noise Precision Amplifiers
General Description
Key Specifications
The LMP8671/2/4 combines great precision, low noise and a
large operating voltage range to provide a high SNR and a
wide dynamic range. Its AC performance allows it to be used
over a wide frequency without degradation. It is the ideal
choice for applications requiring DC precision and low noise
such as precision PLL filters, multi feedback and multi pole
active filters, GPS receivers and precision control loop sys-
tems. The LMP8671/2/4 offers an extremely high open loop
gain of 135dB, low voltage noise density (2.5nV/√Hz), and a
superb linearity of 0.000009%. These characteristics drasti-
cally reduce gain error which is a challenge in accurate sys-
tems requiring higher gains such as data acquisition systems.

Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability
and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in
the Recommended Operating Conditions is not implied. The Recommended Operating Conditions indicate conditions at which the device is functional and the
device should not be operated beyond such conditions. All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 2: The Electrical Characteristics tables list guaranteed specifications under the listed Recommended Operating Conditions except as otherwise modified
or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and are not guaranteed.
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature, TA. The maximum
allowable power dissipation is PDMAX = (TJMAX - TA) / θJA or the number given in Absolute Maximum Ratings, whichever is lower.
Note 4: Human body model, applicable std. JESD22-A114C.
Note 5: Machine model, applicable std. JESD22-A115-A.
Note 6: Typical values represent most likely parametric norms at TA = +25ºC, and at the Recommended Operation Conditions at the time of product
characterization and are not guaranteed.
Note 7: Datasheet min/max specification limits are guaranteed by test or statistical analysis.
Note 8: PSRR is measured as follows: For VS, VOS is measured at two supply voltages, ±5V and ±20V, PSRR = |20log(ΔVOS/ΔVS)|.
