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.
