SJM190BEC01

The SJM190BEC01 is an integrated circuit that is part of the category of Interface devices which include Analog Switches, Multiplexers, and Demultiplexer. This type of device was specifically designed to route analog signals that are typically low-speed, low power, low-voltage signals. It provides both digital input and output connections and includes adjustable power settings to extend compatibility with other electronic components.

The device is composed of four channels of CMOS low power FET switches. The switches can be used in either a single-ended configuration or in a differential configuration as required. It features a wide range of supply voltage from 2.7V to 5.5V, making it suitable for a variety of low voltage applications. All channels have selectable logic polarity which allows for customization to different logic levels.

The SJM190BEC01 has several advantages over other analog switches, multiplexers, or demultiplexers. First, it has low power consumption, and the number of channels it covers is less compared to other similar parts. Furthermore, it incorporates adjustability for the input logic thresholds for each of the channels allowing any number of logic levels to be used. Finally, it includes on-chip protection against voltage fluctuations.

The working principle of the SJM190BEC01 is quite simple. This devices allows analog signals to be routed either directly or via switches and multiplexers. With the digital input and output connections, it is possible to monitor and control the analog signals. Digital control of the channels is made possible by the control logic block, which consists of two stages of logic blocks that allow different levels of logic to be controlled. The first logic block is a basic two-input logic gate, and the second is a Schmitt trigger logic block.

The analog switches inside the SJM190BEC01 device are connected to the control logic, which sets the input/output configuration. According to the input and desired output, the control logic adjusts the on/off states of the FET switches. If the input and output signals need to be in different ranges, the control logic will adjust the corresponding channels in the switch matrix accordingly.

The SJM190BEC01 can be used in a wide range of applications. It is ideal for applications that involve routing low-speed, low power, low-voltage signals and for applications that require protective circuits for voltage fluctuation prevention. It is also suitable for applications that involve the transformation or amplification of analog signals. This device can also be used in biomedical instrumentation or any other application that requires the reliable routing of analog signals.
