Introduction

The LMV881LEE/NOPB is a high performance, low power, low input current instrumentation amplifier designed for a wide range of high-speed applications. Its feature set and high level of integration delivering a very low overall part count make it ideal for a range of medical applications.

Application Field

The LMV881LEE/NOPB is ideally suited for use in medical instruments, imaging systems, and diagnostic equipment when high resolution and accuracy of measurements is required. It can also be used for other applications such as high speed data acquisition, automotive, and general instrumentation.

The amplifier is also suited for applications where very low power consumption and high speed operation is required. It has a wide range of available gains and low offset voltage as well.

Working Principle

The amplifier comprises of five stages comprising a differential input stage, a gain adjusting stage, a current sensing stage, a power-saving stage, and an output stage. The differential input stage allows the LMV881LEE/NOPB to accept a wide range of differential input signals. The feedback resistors, together with the gain adjustment stage, set the gain of the amplifier, allowing gains of up to 50V/V to be achieved.

The current sensing stage regulates the output current to ensure a low noise, distortion free output signal. The power saving stage is used to reduce power consumption and maintain the desired signal accuracy. The output stage enables the output signal to be buffered and can be driven directly with a load of up to 1 μA.

The key features of the LMV881LEE/NOPB amplifier include low noise, low power consumption, low input current, high speed, and wide dynamic range. These features provide an excellent solution for medical instrumentation and general instrumentation applications.

Conclusion

The LMV881LEE/NOPB is a high performance, low noise, low current instrumentation amplifier designed for a wide range of applications. Its feature set and high level of integration make it ideally suited for medical instruments and general instrumentation applications. Its low power consumption, high speed operation and wide dynamic range make it ideal for high resolution measurements and power saving applications.
