TS271CD Application field and working principle

Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The TS271CD is a linear amplifier used in instrumentation applications. It is designed as an operational amplifier (op amp) but also functions as a buffer amplifier. As a low-power amplifier, it provides a wide range of control of the input signal and works well with either AC or DC signals. The TS271CD is designed to yield a low power dissipation per input and output channel (typical 2mW) and a wide operating voltage range of 1.8 to 12V. It is an ideal choice for vibration, background noise and low-frequency applications that require a low-level signal. It is also suitable for preamplification before further signal conditioning. The main principle of the TS271CD is that it amplifies a very small input signal that is created by vibration or other low-level signals and produces a larger amplified output signal by both adding a gain and linearizing the signal. This amplifier notably provides a low-power dissipation, high input impedance, and high accuracy, accuracy being the ability of the amplifier to equally amplify all frequencies of the input signal.The input structure of the TS271CD consists of an operational amplifier, a resistor divider network, and a differential amplifier. The operational amplifier provides a high input impedance that allows additional components to be used in series with the input signal to provide protection against high voltage. The resistor divider network provides a stable DC potential that ensures a low noise operation and a low level of DC offset. The differential amplifier allows the input signal to reach a substantially larger voltage level that is required to drive the output transistors. The output structure of the TS271CD consists of two differential amplifiers and two output transistors. The differential amplifiers provide the necessary voltage swing for the output transistors to properly drive the output signal. The output transistors act as the primary source of gain in the amplifier and are arranged in a class-A common collector configuration. The TS271CD also contains several circuits and resistors for current limiting and protection from overvoltage and excess power dissipation. The performance characteristics of the TS271CD are dependent on the gain and frequency of the input signal. The gain of the amplifier ranges from 1 to 6 dB with a few well-defined low- and high-frequency roll-off points. With a low-level input signal, it can handle a maximum input voltage of ±1V while the maximum output voltage is determined only by the output stage’s transistor characteristics and the operating voltage. The output voltage at 3V operation is usually limited to ±2V, while it peaks at 12V. The TS271CD amplifier is a very reliable and indispensable component in any instrumentation application and has been proven to provide accurate, high-quality amplification of many different forms of signals. Its low power dissipation, small size, and reliable operation make it ideal for a wide range of applications, from low-level voltage measurements to AC signal monitoring and preamplifying. With its wide range of control settings, it is easy to find the perfect configuration for any system and provide great signal amplification with the accuracy and power efficiency you need.
