The TS3A27518EZQSR is an analog multiplexer and demultiplexer device best suited for power efficient, portable battery powered applications. It provides 18 channels of analog switching, making it ideal for applications such as analog signal routing and multiplexing, audio routing and inter-stage signal routing.

The device features an enable input pin that can be used to enable or disable multiplexer and demultiplexer operation. It has a low- voltage operation range of 1.8V-3.6V and can be used with a supply voltage range from 1.8V to 5.5V.

In terms of application fields, the TS3A27518EZQSR is well suited for audio routing, analog signal routing and multiplexing, analog signal measurement, low frequency power switching, inter-stage signal routing in analog signal chain, and other applications benefiting from low-voltage operation.

The working principle behind the TS3A27518EZQSR is based on the use of a single enable input pin. With the enable input pin asserted, the switch will enable selection between two analog signal paths. If the enable input pin is not asserted, the switch will be turned off and no signal paths will be selected.

When selecting an analog path, first the corresponding analog signal is applied to the input of the switch. Then the enable signal is asserted so that the selected analog signal is routed through the enabled switch path. As each enable signal is asserted, the same process is repeated for any of the other analog signals that need to be routed.

When the enable signal is de-asserted, the switch turn becomes off, preventing any signal path selection. When the enable signal is re-asserted, the switch once again enables selection between two analog signal paths.

The TS3A27518EZQSR is also equipped with slew rate control pins that are used to set the rise and fall times of the signals routed via the analog switch. The device comes in a QFN-16 package with a 6 mm2 footprint, allowing it to fit easily into space-constrained applications.

In conclusion, the TS3A27518EZQSR is an ideal device for a wide range of analog signal routing and multiplexing tasks. Its low-voltage operation, fast switching times, and small package make it an ideal choice for power efficient, portable battery powered applications.
