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 systems. 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 drastically reduce gain error which is a challenge in accurate systems requiring higher gains such as data acquisition systems.

To ensure that the most challenging loads are driven without compromise, the LMP8671/2/4 has a high slew rate of ±20V/μs and an output current capability of ±26mA.

The LMP8671/2 family of high-voltage amplifiers are available in SOIC-8, the LMP8674 in SOIC-14.
