The ISL43L840IRZ-T is an interface – Analog Switches, Multiplexers, Demultiplexers solution, offered by Intersil. This device connects 2 channels in bidirectional mode and provides unique flexibility for applications where accuracy and repeatability are the main requirements.

The primary application field of the ISL43L840IRZ-T is the interface between two ports, where multiple switches and multiplexers are needed. This device can be used in different configurations, such as SPDIF (for digital audio signal) and microphone switching. Other industries, where this device finds application, include automotive, industrial, medical, and consumer sectors.

The working principle of the ISL43L840IRZ-T is as follows: two bidirectional analog/digital switches are connected to each other and both separated from their respective ports. The control is then made different including an audible signal or a specific pattern at the input side along with the signal on the output side. The switch then functions accordingly and the connections are made or interrupted depending on the signal received.

For improved performance and better system operation, the device uses its own low power circuitry. This eliminates the need for external power, as the supply can be directly taken from the interface side. Further, this device features an intelligent control, ensuring continuous operations of the system.

The ISL43L840IRZ-T also provides flexibility in terms of the signal types that can be switched, making it suitable for use in noisy environments. Its CMRR of -60 dB and 8-bit PGA make it a highly reliable solution. Additionally, the device offers a wide range of selectable connections and allows for custom switch configurations. The wide range of signal types supported include I2S (I2S Audio), PDM (Pulse-Density Modulation), and PCM (Pulse-Code Modulation). It has an integrated protection against shorts, ESD, and reverse polarity.

Overall, the ISL43L840IRZ-T is an ideal solution for interface – analog switch, multiplexer, and demultiplexer applications. It provides excellent signal transmission, enabling consistent operation in challenging environments. This device is highly reliable and provides excellent sound performance, making it a perfect choice for audio-related applications. With its low-power characteristics, it also offers great value for money.
