FEATURES  
DESCRIPTION  
The LMP8671/2/4 combines great precision, low

Output Short Circuit Protection  
PSRR and CMRR Exceed 110dB  
Best in Class Linearity (135dB)  
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 VOS 2μV/°C (max)  
Power Supply Voltage Range ±2.5V to ±20V  
Voltage Noise Density 2.5nV/Hz  
Slew Rate ±20V/μs  
The LMP8671/2 family of high-voltage amplifiers are  
available in SOIC-8, the LMP8674 in SOIC-14.  
Gain Bandwidth Product 55MHz  
Open Loop Gain 135dB  
Input Bias Current 10nA
