Introduction to the TSV912IQ2T

The TSV912IQ2T is a precision dual, low noise, high bandwidth, and high common mode rejection ratio instrumentation amplifier. This instrumentation amplifier uses advanced SOT-23 technology with advanced temperature stabilization to provide a very low temperature coefficient of gain and offset. It has a common mode input range of ±20V and a closed loop gain range of 500V/V maximum. This amplifier is ideal for applications such as remote sensing, medical instrumentation, and data acquisition systems that require a low noise, high precision signal with low power consumption.

Application field

The TSV912IQ2T is primarily used in applications where high voltage and low noise performance is required. It is used in medical instrumentation and data acquisition systems to measure high voltage signals with low noise and high common mode rejection. It is also commonly used in remote sensing and measuring systems. These applications require a low voltage common mode input range with a high common mode rejection ratio.

Working Principle

The TSV912IQ2T incorporates advanced SOT-23 technology and temperature stabilization to provide low noise, high bandwidth, and a high common mode rejection ratio for low voltage differential signals. This makes it ideal for applications requiring precision gain and/or offset adjustment. The gain of the TSV912IQ2T is adjustable from 0V/V to 500V/V with a closed loop gain accuracy of 0.05%. The offset of the amplitude is adjustable from 0V to ±2V. The common mode input range is ±20V with a differential mode input range of ±2V. The TSV912IQ2T uses three main components to achieve its precision performance. The first is the input differential amplifier stage, which provides common mode rejection and gain. The second is the adjustable gain stage, which adjusts the output of the input differential amplifier. This stage has a gain range of 500V/V and is adjustable by the user. The third stage is the adjustable offset stage which is used to adjust the output voltage from 0V to ±2V.

Conclusion

The TSV912IQ2T instrumentation amplifier is a precision dual, low noise, high bandwidth, and high common mode rejection ratio amplifier. It is used in applications requiring high voltage and low noise performance, such as medical instrumentation, remote sensing, and data acquisition systems. The TSV912IQ2T uses advanced SOT-23 technology and temperature stabilization to provide a low voltage differential input range with a closed loop gain accuracy of 0.05%. With its adjustable gain and offset, the TSV912IQ2T is an ideal amplifier for applications where precision, low noise, and low power are required.
