Instrumentation amplifiers are dynamic devices that are used to amplify the signal of a separate instrument within an electrical system. They are utilized to provide a level of signal amplification that doesn’t distort or degrade the signal. The MCP6402-H/SN is one example of an instrumentation amplifier that can be used for various purposes. This article will discuss the application fields and working principle of the MCP6402-H/SN.

Application Fields

The MCP6402-H/SN is a dual instrumentation amplifier with a maximum gain of 36.3 dB. Its gain is adjustable with a ±18 dB range. It is designed to be used in industrial and automotive applications, particularly when precision accuracy is required in the boosted signal or there is a need for a higher signal integrity. It is a high-performance, low-power amplifier that can be used in a variety of applications such as medical device systems, instrumentation and test equipment, and analog input and output modules. It is also useful in monitoring temperature, pressure, current, and voltage signals in industrial processes.

The design of the MCP6402-H/SN incorporates a wide range of features that make it even more suitable for integration in different systems. These features include low distortion, low input bias current, and low quiescent current. It offers high CMRR (Common Mode Rejection Ratio) and PSRR (Power Supply Rejection Ratio). Additionally, the adjustable gain and adjustable common-mode level makes it an ideal choice for many applications.

Working Principle

The MCP6402-H/SN utilizes an input amplifier stage that is made up of two high-performance input op-amps. The two input op-amps are followed by two complementary buffers that are individually tuned to deliver a precise amount of gain. The gain of each buffer can be set with a pair of external resistors. The op-amps in the input stage amplify the signal to the required level and then it is passed on to the buffering stage. The buffering stage separates the resulting signal from the input stage, ensuring that the signal is precise and free of distortion. The output of the buffering stage is then sent to the inversion stage which inverts the signal. The inverted signal is then passed on to the output stage, where it is amplified and sent to the desired device or system.

The MCP6402-H/SN has several key components that work together to ensure precise signal amplification and low distortion. The input and output amplifier stages ensure that the signal is amplified without losing any of its integrity while the buffering stage provides additional isolation of the signal. The inversion stage takes the signal and inverts it before sending it to the output, which prevents the signal from being distorted by the current in the device. Finally, the adjustable-gain feature enables the amplification of the signal to the required level without any distortion.

Overall, the MCP6402-H/SN is a high-performance, low-power amplifier that can be used in a variety of applications. It is an ideal choice for applications that require a precise level of signal amplification with minimal distortion or noise. The adjustable gain and adjustable common-mode level make it an ideal choice for many applications. Additionally, the low input bias current and low quiescent current make it suitable for integration across a wide range of systems.
