Introduction

The MCP6407T-H/SN is a single-supply, precision CMOS instrumentation amplifier designed for use in demanding high-performance systems. The amplifier can be used to measure voltage differences between two different input signals, perfect for instrumentation, data acquisition and biomedical applications where a wide range of signal amplitudes may be encountered. Operating from a single power supply, the MCP6407T-H/SN is available in an 8-pin SOIC package with a variety of combination pins to accommodate different installation options. The MCP6407T-H/SN is also compatible with low-level inputs, supporting an upper reference voltage range of 4.5V-12V and a lower reference voltage range of 0V to 0.3V.

Application Field

The MCP6407T-H/SN’s feature set makes it an excellent choice for a variety of applications, particularly instrumentation, data acquisition, and biomedical uses. Its low-level input range makes it suitable for measuring and amplifying very low-level signals such as bioelectrical and biomedical signals, which require very sensitive amplifiers. Its high dynamic range makes it well-suited for use in instrumentation and data acquisition systems, making it possible to measure and amplify signals within a wide range of amplitudes. The MCP6407T-H/SN can also be used in high-performance applications such as voltage-controlled oscillators and audio applications.

Working Principle

The MCP6407T-H/SN comprises a differential input instrumentation amplifier stage and a variable-gain buffer stage. The differential input stage provides the amplifier with a high input impedance and excellent Common-Mode Rejection Ratio (CMRR). The variable-gain buffer stage allows the user to set a gain from 1 to 64, depending on their application requirements. This can be done using the external precision resistors and gain set resistors.The amp has four input pins and four output pins that provide the user with the flexibility to choose how they want to control the amplifier. For example, the MCP6407T-H/SN can be connected with a single input pin to generate a high-impedance output, which is useful in many data acquisition systems. The amplifier also has an input offset pin that allows the user to trim the DC offset voltage to optimize the gain accuracy.

Conclusion

In summary, the MCP6407T-H/SN offers an excellent solution for a variety of applications requiring precision and flexibility in its operation. Its low-level input range makes it suitable for measuring and amplifying very low-level signals such as bioelectrical and biomedical signals. Its high dynamic range makes it well-suited for instrumentation and data acquisition systems. Finally, its adjustable gain stage allows the user to adjust the gain from 1 to 64, making it suitable for a wide range of applications.
