LT1568CGN#TRPBF

The LT1568CGN#TRPBF is a Low-Noise and High-CMRR operational amplifier (op amp) with a GBWP of 1kHz and a slew rate of 11.5V/μs. This part is designed for high-side current sensing applications. It has a wide common-mode range of ±12V and a fixed shutdown disable mode. This feature allows for a very low operating voltage of 3V (±1.5V). With an excellent noise performance, it can be used for low-noise applications. When used in low-noise amplifiers, it provides superior sound quality.

Applications

The LT1568CGN#TRPBF is suitable for audio applications, power amplifiers, sample and hold circuits, integrators, peak detectors, logarithmic amplifiers, voltage-controlled amplifiers, and other general-purpose amplifiers. In addition, this part can be used in high-side current sensing applications. It has an excellent total output error of ±1ppm/°C, making the part ideal for temperature-sensing applications. It can also be used in noise-sensitive applications such as low-noise preamps and low-noise linear regulators.

Features and Benefits

The LT1568CGN#TRPBF features a wide common-mode range of ±12V, allowing it to be used with a variety of power supplies. It also features a fixed shutdown disable mode, permitting the op amp to be placed in a low-power standby mode. Additionally, the part has a wide bandwidth of 1kHz and a slew rate of 11.5V/μs. This makes the part suitable for fast response circuits, such as in low-delay amplifiers. Its excellent noise performance makes it ideal for low-noise applications. It is also designed with a high common-mode rejection ratio (CMRR) of 100dB, exceeding the requirements of most applications. This ensures the output is not affected by common-mode signals, such as those found in audio applications.

Working Principle

The LT1568CGN#TRPBF is an integrated circuit that consists of three stages: an input stage, a compensation stage, and a power stage. The input stage consists of two matched input transistors and two matched resistors that form an differential amplifier circuit. This stage amplifies the input signal, while rejecting any common-mode voltages that may be present. The second stage is responsible for providing the phase compensation necessary for high-frequency stability in the circuit. This stage uses a combination of capacitors and resistors which form a phase compensation network to ensure the amplifier circuit is stable. Finally, the power stage uses a pair of N- and P-channel MOSFET transistors in a common-source configuration to amplify the signal. The output signal is then directly loaded onto the powerstage, and the output signal is taken from the output power transistor.

Conclusion

The LT1568CGN#TRPBF is a low-noise and high-CMRR operational amplifier that is designed for high-side current sensing applications. It features a wide common-mode range of ±12V, and a fixed shutdown disable mode. In addition, the part is suitable for use in audio applications, power amplifiers, sample and hold circuits, integrators, peak detectors, logarithmic amplifiers, voltage-controlled amplifiers, and other general-purpose amplifiers. It is also designed with a wide bandwidth of 1kHz and a slew rate of 11.5V/μs, making the part suitable for fast response circuits. Furthermore, it has an excellent noise performance, making it suitable for low-noise applications.
