LTC1264-7CSW#TRPBF

LTC1264-7CSW#TRPBF is an active interface filter designed to filter, protect and isolate input signals from hazardous ground loops. It has a wide range of applications in computer, industrial, and automotive industries to filter, protect and isolate input signals from hazardous ground loops. This filter is ideal for applications that require high performance protection and isolation at very low supply current, without compromising signal integrity.

Introduction:

The LTC1264-7CSW#TRPBF filter provides high-performance passive filtering and active isolation between a system’s low-level and high-level input signals. This helps protect point-to-point communication links from ground loop problems such as noise, overload and RFI/EMI. Additionally, since the filter is an active device, it operates at low currents and is not affected by the relatively long trace lengths associated with high-speed applications.

Application Field:

The LTC1264-7CSW#TRPBF filter is suitable for a wide range of applications in computer, industrial, and automotive industries. It can be used to filter, protect and isolate input signals from hazardous ground loops in automotive signal inputs, point-to-point communications links, and signal conditioning noise issues.

Due to its low supply current and signal integrity characteristics, the filter is also well suited for data acquisition, signal conditioning, and other communication systems. It is suitable for use in applications that require minimal signal degradation, such as industrial control systems, local area networks, and automation.

Working Principle:

The LTC1264-7CSW#TRPBF is a passive filter with active isolation circuitry. The passive filter is implemented with two levels of passive filtering, which remove unwanted noise and spikes, so that problem signals are not allowed to propagate to the active circuitry. The active circuitry is designed to provide a lowpass filter and spread-spectrum noise filter. This circuitry is powered by a low-level AC supply. The lowpass filter passes the signal at the desired frequency and suppresses higher frequency noise. The spread spectrum noise filter suppresses any narrowband noise that may be present, allowing the signal to remain consistent.

Conclusion:

The LTC1264-7CSW#TRPBF is an active interface filter designed to filter, protect and isolate input signals from hazardous ground loops. It is ideal for applications that require high performance protection and isolation at very low supply current, without compromising signal integrity. The filter provides high-performance passive filtering and active isolation between a system’s low-level and high-level input signals, making it suitable for point-to-point communication links and signal acquisition systems. The filter is composed of both passive and active circuits and is powered by a low-level AC supply.
