Introduction

The TSZ124IQ4T is a high performance amplifier used in a wide range of instrumentation, operational amplifiers (op amps), buffer amplifiers, linear amplifiers, and other calibration and test equipment. This application note provides an overview of the design principles and application fields of the TSZ124IQ4T. It describes the key features and the different types of TSZ124IQ4T amplifiers, as well as the design of the various components used in the design of the TSZ124IQ4T.

General Description

The TSZ124IQ4T instrumentation amplifier is a low-noise, low-bandwidth, precision amplifier that offers excellent linearity, high common-mode rejection ratio (CMRR), low distortion, and low offset voltage. It is designed for use in a wide range of applications including high-resolution analog-to-digital Convertors (ADCs), DC and switching power supplies, data acquisition systems, and other systems requiring precise, repeatable measurements. The TSZ124IQ4T is data-sheet-programmable, can be used as a second-order Butterworth highpass filter, and has built-in electronic protection circuitry.

Design Principles

The TSZ124IQ4T amplifier is a four-stage differential amplifier diagram which consists of two differential pairs and two current sources. The differential pairs act as the main gain stages and each has its own complementary metal-oxide-semiconductor (CMOS) input transistors. A series of feedback resistors connect all the components in order to achieve the desired gain and stability. The output of the differential pairs is then buffered by the two current sources, which provide additional power gain and stability. By adjusting the feedback parameters, the amplifier can be programmed to provide very precise gain response.

Application Field

The TSZ124IQ4T amplifier is ideally suited for instrumentation, operational amplifiers, linear amplifiers and buffer amplifiers. It is commonly used in data acquisition systems where precise, repeatable measurements are required. It is also ideal for applications that require excellent linearity, low distortion and low offset voltage. Applications such as high resolution analog-to-digital convertors, DC and switching power supplies and other systems requiring precise, repeatable measurements are all ideal applications for the TSZ124IQ4T.

Working Principle

When an input signal is applied to the TSZ124IQ4T amplifier, the output signal is determined by the gain of the differential pairs, which is set by the feedback resistors. The current sources provide additional power gain and stability, allowing for a more precise and repeatable output. The high performance characteristics of this amplifier allow for excellent linearity, low distortion and low offset voltage. Additionally, the electronic protection circuitry provides protection against overvoltage, overcurrent and thermal runaway.

Conclusion

The TSZ124IQ4T amplifier is a high performance amplifier used in a wide range of instrumentation, operational amplifiers, linear amplifiers and buffer amplifiers. Its design principles allow for excellent linearity, low distortion and low offset voltage, making it an ideal choice for systems requiring precise, repeatable measurements. The data-sheet-programmable feature of this amplifier allows for flexibility when setting the gain, and its built-in protection circuitry ensures safety and reliability.
