Check for Samples: LMP8671, LMP8672, LMP8674 FEATURES 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/в€љHz), 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. 1 2 Output Short Circuit Protection
