TS1874IPT Integrated Circuits (ICs)

Linear: Amplifiers: Instrumentation, OP Amps, Buffer Amps

Analog Devices TS1874IPT is a high-performance instrumentation amplifier. This device is designed for professional audio-video systems where low noises, high accuracy and millisecond switching need to be achieved. This product is part of the Linear Amplifier family, which includes OP Amps, Buffer Amps and Instrumentation Amplifiers. The TS1874IPT is has a low offset voltage, a large dynamic range and a high common-mode rejection ratio (CMRR). Besides, it contains three gain-setting pins which could adjust the gain precisely.

Application

The TS1874IPT can be applied to many professional audio-video systems and laboratories. For example, sensor interfacing systems, AC/DC signal conditions, impedance measurements, and medical biosensors. Due to its low noise, ultra-low offset voltage and high common-mode rejection ratio, it is suitable for applications where accuracy and precision are critical. Additionally, the adjustable gain allows engineers to deploy versatile solutions for relevant problems.

Working Principle

The TS1874IPT is based on a three-stage topology. The first stage comprises of a single differential input stage and two variable-gain amplifiers. The variable-gain amplifiers adjust the gain when the three gain setting pins are driven. At the second stage, the differential signals are amplified, thus improving the signal-to-noise ratio. At the third stage, the differential signals are converted to single-ended outputs. The current feedback loop ensures low noise, high speed and high common-mode rejection ratio.

Conclusion

The TS1874IPT is a high-performance instrumentation amplifier ideal for professional audio-video systems. With its low offset voltage, high dynamic range, low noise, adjustable gain and high common-mode rejection ratio, it is suitable for applications that require accuracy and precision. The three-stage topology, especially with the current-feedback loop, ensures excellent performance for many applications.
