Single, Dual, and Quad 40V Low Noise Precision Amplifiers

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/√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.

APPLICATIONS

•

Low Noise Industrial Applications Including

Test, Measurement, and Ultrasound

•

Precision Active Filters

PLL Filters

4-20mA Current Loops

Motor Control

KEY SPECIFICATIONS

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.

•

Input Offset Voltage 0.4mV

TC V_OS2μV/°C (max)

Power Supply Voltage Range ±2.5V to ±20V
