Analog switches, multiplexers and demultiplexers are all devices used to process and control analog signals, but their operation and structure differ from each other. The MAX14758EUE+ is a low-voltage, low-current, low-charge injection analog switch/multiplexer/demultiplexer device intended for a wide range of applications in the interface world. It provides 1/0/1 logic signal switching, as well as 1-in/2-out and 2-in/1-out multiplexing and demultiplexing functionality.

Applications:

The MAX14758EUE+ is an ideal analog switch/multiplexer/demultiplexer solution for a variety of different applications in the interface world. It can be used as a signal switch in audio and video system circuitry where isolation between analog signals and digital logic is essential. The device is also suitable for use in processors or microcontrollers to multiplex and demultiplex digital signals. Other applications include sequencing and storing digital data, motor control, communications, and power management.

Working Principle:

The MAX14758EUE+ provides low-voltage, low-current, low-charge injection analog switching/multiplexing/demultiplexing. It works by switching between two or more input signals with a minimum of on-resistance. The device has two “A” and two “B” channels, which can be connected in series or parallel to provide higher voltage and current ratings. It also features charge injection suppression capacitors and a low-voltage CMOS input buffer. The device is capable of operating at up to 5.5V with a minimum of 1mA current.

The device also features internal logic to ensure that only one side is selected at a given time. A logic input is provided to select between channels A and B, and when in the correct state, the channel will automatically be selected. If a logic input of ‘0’ is used, the channel with the highest priority will be selected. This selection is carried out automatically and is done independently from any other logic or control signal. The device also features an enable/disable pin that can be used to remotely control the switch.

The MAX14758EUE+ is an ideal device for applications that require low-voltage, low-current, low-charge injection analog switching/multiplexing/demultiplexing. Its low charge injection and power consumption make it an ideal choice for a variety of interface applications. With its internal logic and enable/disable pin, the device can be used as a switch, multiplexer, or demultiplexer, providing a solution for a broad range of interface applications.
