Instrumentation amplifier is widely used for various application fields such as medical, measurement and industrial control. Linear Technology\'s LMP8640HVMK-H/NOPB is an ultra low-power precision quad precision instrumentation amplifier that can accurately measure small signals in the presence of high common mode transients. Its unique design embodied in its versatile pin configuration, allows it to easily be used in a broad range of high precision circuit applications.

The LMP8640HVMK-H/NOPB is made with a low input bias current on all four inputs, which makes it ideal for low voltage designs in both industrial and medical applications. It is capable of providing high common mode rejection and excellent input offset voltage accuracy while working with high speed precision amplifiers. The amplifier\'s high resolution, low offset and low-noise characteristics provide accurate results in both gain and measurement in harsh environment.

The LMP8640HVMK-H/NOPB has an open loop gain of 80dB, which provides an excellent front end for high speed input signals. It features four independent inputs/outputs for precision low-drift operation and different programmable gain settings. On its output, the LMP8640HVMK-H/NOPB has an adjustable voltage range for both low-side and high-side outputs. This output voltage range feature allows the user to easily optimize the amplifier\'s output performance for a particular application.

The working principle of the LMP8640HVMK-H/NOPB is based on a combination of multiple circuits used in instrumentation amplifiers. The quad precision instrumentation amplifier consists of two differential input amplifiers, two gain setting circuits, a two-pole filter and an output buffer. The two independent differential input amplifiers provide an input signal gain of up to 20dB and a frequency response of 100kHz. The two gain setting circuits ladder the amplifier\'s gain and provide voltage gain settings of up to 40dB with a total gain of up to 80dB. The two-pole filter provides a low-frequency roll-off, which allows the user to adjust the transfer characteristic of the amplifier. The output buffer provides protection for the amplifier and saturation of the output to the intended level.

The multiple circuit configuration of the LMP8640HVMK-H/NOPB provides the user with a flexible, yet precise instrumentation amplifier for a wide range of applications. The low-side and high-side output adjustments allow the amplifier to be configured for various gain settings, offset adjustments and output protection. In addition, the amplifier has a low input bias current for low voltage designs and operating temperature ranges of -40°C to 125°C.

The LMP8640HVMK-H/NOPB is a versatile instrumentation amplifier suitable for a broad range of circuit applications. The amplifier has an open loop gain of 80dB, which is ideal for low power designs, as well as low noise and high common mode rejection. The adjustable voltage range on its outputs allow the user to easily optimize its output performance for a particular application. Whether a system needs to measure small signals in the presence of high transients or provide protection for sensitive components, the LMP8640HVMK-H/NOPB provides the user with the right solution.
