Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The TSV991IQ2T is an instrumentation amplifier which belongs to the Linear technology family. It is basically used for signal voltage and current amplification, where its working principle is basically integrated with the Voltage-to-Current (ViC) conversion technology. This instrumentation amplifier integrates two virtual ground configurations, which have the ability to deliver high frequency signals up to 12MHz. It also includes low frequency feedback, high frequency output stabilizing, and gain settling.

This amplifier offers a common-mode range of -14V to +14V and for power supply, it requires a dual-supply voltage range of +0.4V to +7V, and -7V to -0.4V in order to deliver an optimal performance. Furthermore, it contains an inefficient supply current than other comparable amplifiers, which allows for an enhanced power conservation. It also has a low output-offset voltage which allows it to perform with an enhanced precision and accuracy.

The working principle for the TSV991IQ2T instrumentation amplifier is based upon several referenced input and output stages. All these stages interact with each other to amplify the incoming signals. The input stage has four transistors that are used to create a differential stage configuration, which allows the amplifier to convert the incoming input signals into a weak current. This weak current is then inverted by a complementary pair of transistors and then used as a fundamental input signal for the second stage.

Next, this weak current is processed by an auxiliary inverting stage to create a bipolar input signal. This bipolar input is then passed to the current to voltage (C2V) converter stage, where it is converted into an output voltage. This output voltage is then used as a reference for further stages. After this, the precisely proportioned amplified output is generated by passing the input signals through a precision amplifier.

The TSV991IQ2T Amp is specifically designed for various applications that require amplifying weak signals such as medical systems, instrumentation and process control systems, and industrial monitoring systems. It is also well-suited for AC and DC voltage measurements, as its circuit configuration is quite stable in the presence of major voltage variations. Furthermore, it is also compatible with various bridge completion techniques such as Wheatstone bridge, Kelvin bridge, and Jenson bridge.

In summary, the TSV991IQ2T amplifier is a robust and reliable instrumentation amplifier that is commonly used for low noise and low power applications. Its working principle has been designed to convert weak input levels into higher output voltage levels with accuracy and precision. It is also well-suited for use in various industrial applications that require accurate signal amplification.
