LTC1068-50IG#TRPBF

The LTC1068-50IG#TRPBF is an important component in the field of active interface filters used in a variety of applications. The active filter is designed to suppress alternating current (AC) noise from interfering with sensitive electronic components, like microprocessors and control circuits. This article will discuss the application field and working principle of the LTC1068-50IG#TRPBF active filter.

Applications

The LTC1068-50IG#TRPBF active filter is most commonly used in applications that require high-frequency electronic noise to be blocked or suppressed. Examples of such applications are the suppression of electromagnetic interference (EMI) noise in motor speed sensing applications, power surges and spikes in automotive electronics, avionics systems, and medical equipment. The active filter is also well-suited for use in AC-coupled amplifiers, DC-coupled amplifiers, and other high-frequency applications.

Design & Working Principle

The LTC1068-50IG#TRPBF is a surface mount component that incorporates a three-terminal active filter. The component consists of two transistors and two resistors. The transistors are wired in the form of a differential amplifier, which is the basic building block of many noise-suppressing active filters. The two transistors serve as the inputs, while the resistors serve as the output and control terminals. When an AC signal is applied to the input terminals, the differential amplifier works to remove any noise present in the signal by amplifying and applying a small AC voltage to the output terminals.

The component is also equipped with two filter capacitors, which are used to filter out any additional high-frequency noise that may be present in the signal. The capacitors serve as a low-pass filter, allowing only lower frequency signals to pass through. The component also features a protective circuit, which prevents the component from becoming damaged due to excessive current.

Overall, the LTC1068-50IG#TRPBF is a highly effective active filter component. It is well-suited for applications that require the suppression of high-frequency noise and is designed to last for extended periods of time. The component is easy to incorporate into any circuit, and its small size makes it a great choice for applications where space is at a premium. Additionally, the component is relatively inexpensive, making it a great choice for budget conscious consumers.
