The LMP8640HVMKE-H/NOPB is an instrumentation amplifier from Texas Instruments. It is a monolithic integrated circuit designed for precision signal conditioning applications. It is available in a SOIC-8 package and has an input voltage range of ±10 V. It is designed for applications with both low and high common mode voltages, such as power supply monitoring, sensor measurement, and ADC input conditioning.

The LMP8640HVMKE-H/NOPB is a low-power amplifier that provides high-precision gain accuracy, high CMRR (common mode rejection ratio), and an input range of ±15V. It also features an adjustable gain and filter settable bandwidth, as well as a low input bias current, making it an extremely reliable instrumentation amplifier suitable for a range of applications.

The device is ideal for applications where offset voltage, gain accuracy and common mode rejection ratio are critical. It consists of three parts: two input stages, an output stage and a gain stage. The two input stages are differential amplifiers consisting of two pairs of input transistors and one pair of feedback transistors. This allows for a wide differential input range. The output stage and gain stage consist of two pairs of transistors and two transistors, respectively. This allows for an adjustable gain. The LMP8640HVMKE−H/NOPB uses high-performance current mirrors for gain buffering, with a gain range of ±10V or 20V.

The LMP8640HVMKE−H/NOPB uses a series of internal passive elements to provide a high common-mode rejection ratio. The series consists of a capacitor, resistor, and inductor. These components reduce noise, improve the device’s dynamic range, and tone down any high-frequency transients. This allows the device to have a minimal effect on input signals, while still providing a wide common-mode range.

The LMP8640HVMKE−H/NOPB is ideal for applications where precision and accuracy are paramount. It is particularly useful for power supply monitoring, sensor measurement and ADC input conditioning. It can also be used for applications such as DSP interface conditioning, instrumentation, test and measurement, and medical equipment. The device\'s features provide the flexibility to achieve performance far beyond that of traditional instrumentation amplifiers.
