LMC6464AIM Application Field and Working Principle

Introduction

The LMC6464AIM is an ultra-low-noise, low-offset, low-power CMOS dual-channel instrumentation amplifier. It is a monolithic integrated IC designed specifically to measure tiny differential signals such as those typically found in industrial and medical instrumentation, process control and embedded sensing applications. The LMC6464AIM provides two or four channels of differential inputs and offers a wide range of gain ranges, low offset, low noise and low power consumption, making it an ideal solution for low-power, space-constrained instrumentation applications. The device offers a wide power supply behavior, allowing for a supply spectrum from as low as 1.8V to as high as 5.5V, allowing for maximum design flexibility.

Application Fields

The LMC6464AIM is an ideal amplifier for sensor, data acquisition, and industrial instrumentation applications. It is suitable for low-offset, low-power, ultra-low-noise differential signal measurements, including scaling and level shifting for any signal conditioner and A/D converter. The device is also ideal for high-resolution strain gauge, bridge and weight measurements. Linear temperature measurements, such as RTD, thermocouple, thermistor, and Pt100/200, can be implemented with the LMC6464AIM. Additionally, it can also be used in biomedical and bioelectrical applications.

Working Principle

The LMC6464AIM is a true differential amplifier. Its two or four channels are configured as high-gain differential gain stages driven by a high- input impedance two-stage common mode amplifiers (CMAs). A pair of integrated resistors allows for an easily configurable gain stage. A wide input range can be achieved when the resistors are set externally to a very low value. The device operates from a single supply and includes an unmatched buffer stage with a wide power supply range. Internal gain setting is supplemented by external gain gain resistors, allowing for gains from unity to a maximum of 1000 V/V. Offset adjustment is achieved through the differential input and gain potentiometers. The device offers a wide power supply range from 1.8V to 5.5V, thus allowing for a variety of applications. Its single-supply operation greatly simplifies the design of dual-supply and power-down applications. This device also offers an integrated, low-offset, three-stage CMOS output stage that provides an ultra-low noise output. In addition, the LMC6464AIM operates with a wide common-mode input range and a low 0.85V internal offset.

Conclusion

The LMC6464AIM is an ultra-low-noise, low-offset, low-power CMOS dual-channel instrumentation amplifier. Its wide power supply range and low offset makes it an ideal solution for low-power, space-constrained instrumentation applications. It is suitable for low-offset, low-power, ultra-low noise differential signal measurements, including scaling and level shifting for any signal conditioner and A/D converter. It can also be used in biomedical and bioelectrical applications.
