The TSH80ILT is a special instrumentation amplifier distinguished by its extremely high linearity, providing great potential for application in a range of scientific, industrial, and commercial applications. It was developed for use in high-precision applications, such as measuring low-level signals in noise environments. The TSH80ILT\'s unique features allow it to deliver accurate measurements at much lower noise levels than other instrumentation amplifiers.

The TSH80ILT is a versatile linear amplifier, containing two stages and supporting both differential and single-ended inputs. Equipped with precision resistors, the TSH80ILT calculates the differences between two inputs to produce the required output. This differentiator feature allows the amplifier to calculate specific higher-order derivatives. Furthermore, the TSH80ILT can be used to construct various other active filters, and amplify very weak signals.

Working Principle

The TSH80ILT is based on the VCVS instrumentation amplifier architecture, which involves two op-amps: one for differential input, and a second for the output driving stage. The operational amplifiers used in this circuit are high-voltage, single-supply types such as the TSH80ILT, so that a power supply voltage of up to 18V can be used. The high-voltage operational amplifiers and the precision resistors used in the circuit contribute to the instrumentation amplifiers’ high linearity.

At the amplifier’s input stage is a differential pair with a low input impedance, which ensures that the amplifier\'s output follows the differential input voltage very accurately. Thanks to the differential input stage, the TSH80ILT can effectively reject any common-mode signals that appear on both inputs. Furthermore, the TSH80ILT circuit employs an output buffering stage, which makes it possible to drive high-impedance loads with ease.

The TSH80ILT also makes use of negative feedback to regulate the open-loop gain of the amplifier. This helps reduce the amplifier’s output to a very stable and predictable value, even when the input may change over time. The amplifier’s open-loop gain is adjustable with a single feedback resistor, which can be used to control the gain for the various applications.

The TSH80ILT’s unique features that contribute to its excellent linearity include its precision resistor, high-voltage operational amplifiers, and adjustable input bipolar offset. Combined with its powerful output-buffering stage and differential input stage, these features provide a very accurate and controllable linear amplifier that can be used in a variety of applications, such as measuring low-level signals in noisy environments.
