Linear amplifiers are a type of electrical component used to amplify an electrical signal having minimal distortion and the flexibility to accommodate a wide range of input signals. Special purpose amplifiers such as the LTC6360HDD are used to meet the unique requirements of many applications. This article will provide an overview of the application fields, as well as discuss the working principle of the LTC6360HDD amplifier.

Application fields

The LTC6360HDD amplifier is specially designed for applications that require power with high signal integrity, including non-linear audio, video, and RF signal processing. The amplifier\'s wide bandwidth and high slew rate make it suitable for signal bandwidths higher than 100MHz. It is also ideal for powering high-sensitivity signal processing circuitry, including voltage and current transducers, and component compensation circuitry. Furthermore, the amplifier can be used to power ultrasound and ultrasound imaging equipment, as well as monitor systems with precision control features. In addition, its high power density, low power consumption, and high output impedance make it an ideal choice for powering medical devices, communication and computing equipment, and industrial automation systems.

Working Principle

The LTC6360HDD uses a differential amplifier design with an internal current feedback loop to produce accurate, stable voltage gains and low noise levels. The differential amplifier consists of two operational amplifiers (OPAMPs) working together to amplify a differential signal. The differential voltage is converted to a single-ended signal, which is then fed back to the OPAMP through the current feedback loop. This feedback loop helps to ensure that the amplifier maintains the desired gain and feedback levels. In addition, the amplifier also employs high speed transistors, known as Class AB transistors, to minimize distortion and ensure linear behavior.

The output of the amplifier is determined by the current gain of the internal feedback loop, which is adjustable via a gain control knob. As the knob is rotated, the output voltage of the amplifier is increased or decreased accordingly. The amplifier\'s output power is determined by the current output limit, which is specified at the factory and cannot be changed by the user. The amplifier is protected from over-current, over-voltage and under-voltage conditions, enabling it to operate safely, reliably, and without interruption in a wide variety of applications.

Conclusion

The LTC6360HDD is a special purpose amplifier designed for applications requiring power with high signal integrity. Its differential amplifier design and current feedback loop help to ensure linear behavior and accurate, stable voltage gains. The amplifier offers high power density, low power consumption, and high output impedance, making it an ideal choice for powering medical devices, communication and computing equipment, and industrial automation systems.
