The LT6555CGN#PBF is an integrated circuit designed for specialized applications which include analog switches, sample and hold circuits, signal routing and signal conditioning. It can be used as a universal signal controller and provides high level of performance. The LT6555CGN#PBF features a wide range of features such as an adjustable sample/hold time, low power consumption and precision signal routing capabilities.

The LT6555CGN#PBF is a programmable analog switch which provides high level of precision and control for the input/output signals. The device is available in four versions, each providing different levels of adjustment for the signal routing process. The first version is the ‘GPL’ (General Purpose Latency) which provides adjustable sample/hold time and is suitable for low-speed signal routing applications. The other three versions are the ‘HSL’ (High Speed Latency), ‘HPL’ (High Precision Latency) and ‘HRL’ (High Reliability Latency). All versions employ a ‘switch’ device to provide signal routing capabilities while the ‘HPL’ version also features a separate ‘analog switch’ device which provides precision control over the input/output signals.

Working Principle

The LT6555CGN#PBF is based on a special combined switch/analog switch concept, which provides the user with increased flexibility and control over the signals routed through the circuit. Basically, the device provides two separate paths; one path is designed to execute the task of complex signal routing while the other is designed to provide a high-precision analog switch for the input/output signals.

The LT6555CGN#PBF is a ‘switchable’ type of device which utilizes the combined switch/analog switch concept to control input/output signals. This control is achieved through the use of two separate paths; one path is used for signal routing and the other is used for controlling the analog switch device. In order to use this concept, the device must be configured in such a way that it can switch either the signal routing path or the analog switch path depending on the signal sent through it.

The signal routing path is based on a special ‘latency’ configuration which allows the signal to be routed to the correct output depending on the input signal level. When the signal is received, the device can decide whether the signal should be routed through the analog switch path or sent directly to the output. The signal then passes through an adjustable delay line which determines how long it takes before the signal is sent to the output. This adjustable delay line is used to make sure that the signal takes the same amount of time to reach the output regardless of the signal level.

The analog switch of the LT6555CGN#PBF is divided into two sections; one section is used for controlling the signal routing feature and the other for controlling the analog switch. For example, the signal routing section can be used to configure the device so that it will route the signal from the input to the output without any modification, while the analog switch section can be used to configure the device to switch the input/output signals depending on the input signal level. The user can also customize the configuration of the analog switch to provide precision control over the input/output signals.

Application Field

The LT6555CGN#PBF is an ideal solution for applications requiring adjustable sample/hold time and high level of precision for the input/output signals. It is well suited for low-speed signal routing applications, such as audio signal routing, analog video signal processing and switching, data conversion and telecommunication systems. It can also be used in digital audio processing systems and communication systems. It is widely used in motion control applications and digital video systems. Due to its wide range of features and flexibility, the LT6555CGN#PBF is currently used in a variety of fields including industrial, commercial, military and automotive markets.
