TS274AIPT Application Field and Working Principle
The TS274AIPT from Texas Instruments is a single supply, low power dual monolithic op-amp featuring integrated thermal shutdown protection. With its unique TS274AIPT topology and low bias current, 2.2V to 6V rail-to-rail input and output operation and low supply current, the TS274AIPT is immensely popular in a wide variety of applications. Not only this, but the Ts274AIPT also comes with excellent input-referred noise performance, making it perfect for a variety of sensitive applications, albeit those of a low-end nature.Overview of the TS274AIPT
The main features of the TS274AIPT include its low power, high speed and excellent temperature stability, which are beneficial in a range of applications. It has a very low input offset voltage (6 mV max) and high common-mode rejection ratio (85 dB at 10kHz). This makes it ideal for audio, power management and precision applications. It also has a high slew rate of 16V/μs, making it suitable for high-speed applications. The TS274AIPT’s unique topology ensures the op amp can operate with low quiescent current (1.4 mA typical for two Op amps). It also has wide operating voltage range, making it suitable for a huge range of applications.Applications of the TS274AIPT
The TS274AIPT’s wide operating range and low power make it ideal for battery-powered applications. It is also suitable for low voltage, low power, and low noise applications such as audio, data acquisition and signal conditioning, including audio signal preamplification, filter circuits and sigma-delta converters. Its low quiescent current and wide operating voltage range (2.2V to 6V) also makes it suitable for applications such as WiFi radios and wireless sensor networks. Its low bias current, low power and excellent PSRR also make it suitable for embedded processing, instrumentation and data acquisition systems.Working Principle of the TS274AIPT
The TS274AIPT is basically a dual Op-Amp which can work with a single power supply. Its internal voltage amplifier is based on a complementary pair of devices (an n-channel and p-channel MOSFET pair) which is connected to the supply rails. This ensures that a regulated voltage across the device is provided and the output voltage can never rise above the supply voltage or sink below ground. The amount of current that can be drawn through the Op-Amp is limited by the resistor connected between the output terminal and the device’s internal voltage amplifier.The device also features a voltage feedback loop which actively adjusts the output voltage according to the input signal. This loop is composed of two resistors which connect the output to the positive and negative supplies. When the input voltage changes, the voltage at the output terminal also changes. This change in the output voltage is then fed back to the input side of the Op-Amp to keep the output voltage constant for a given input voltage.Conclusion
The TS274AIPT from Texas Instruments is a great device for low power, wide operating voltage range and high-speed applications. It has an excellent common-mode rejection ratio of 85 dB and its unique topology ensures a low quiescent current and high accuracy. As such, the TS274AIPT is ideal for audio, power management, embedded processing, instrumentation and data acquisition systems.The specific data is subject to PDF, and the above content is for reference
