DESCRIPTION

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.
