The LMV722MX is an instrumentation amplifier consisting of an internally compensated amplifier and a high-performance 2.5V, 3V, or 5V voltage reference, integrated into a single chip. When used as an op amp, it has the ability to reduce noise, increase accuracy and increase response speed. The LMV722MX signal conditioning amplifiers are designed to handle signals at the edge of the signal range, offering good dynamic range and precision in a wide variety of applications. The versatile amplifier can be used in a variety of applications, including audio, industrial automation, automotive, and medical.

The LMV722MX application field comprises precision instrumentation, sensor conditioning, linear amplification, and signal conditioning. It has a tightly coupled common-mode voltage reference, allowing for high-gain amplification of signals near the operating voltage range. This makes it ideal for accurate thermocouple measurements and other highly reliable signals. The on-chip voltage reference has a 4.096V output voltage, allowing for precise signal conditioning across a broad range of applications.

The working principle of the LMV722MX is based on the doctrine of virtual grounding, which allows the amplifier to have a high open-loop gain. When this high gain is combined with the included voltage reference, the resulting signal is extremely accurate and precise. The input buffer amplifiers are designed to reduce loading and increase gain, while the output buffer amplifiers resist noise and distortion, producing accurate, low-distortion gain up to 20. A low power consumption of just 6mA makes this amplifier suitable for battery-operated devices.

The LMV722MX is an ideal solution for applications requiring accurate signal conditioning in the presence of high-frequency environmental sources. The low-noise amplifier offers a wide gain bandwidth and high-immunity to common-mode noise, making it suitable for precision measurement and data acquisition. The integrated voltage reference also ensures that the amplifier has exceptional frequency response, allowing for accurate results from a wide range of applications. In addition, the amplifier can operate from 5V or 2.5V supplies, allowing for greater versatility.

The LMV722MX is an excellent solution for applications where high gain and precise performance are required. Its ability to reduce noise and increase accuracy makes it an attractive choice for a wide range of applications. Furthermore, its low power consumption and low cost make it an ideal choice for cost-sensitive designs. The amplifier also offers excellent immunity to common-mode noise, allowing for accurate readings across a broad range of applications. With all these features, the LMV722MX is an excellent choice for a range of signal conditioning applications.
