ADG5249FBRUZ-RL7 is a member of the Analog device family of analog switches, Multiplexers and Demultiplexers. It is a dual-channel switch and multiplexer with shock-proof analog — ideal for applications such as driving low-impedance circuitry, buffers, buffering analogue signals, or provide isolation in the event of overvoltage or EMC interference.

This device offers several advantages over other single-ended or differential multiplexers. It features a low input voltage for signals combined with low on-state resistance (RON) and fast switching speeds. The ADG5249FBRUZ-RL7 can be used as a switch, multiplexer, or both together in a multiplexer/switch combination.

ADG5249FBRUZ-RL7 application field includes driving low-impedance circuitry, buffering analogue signals, or providing isolation in the case of overvoltage or EMC interference. Its on-state resistance is less than 5 ohm, enabling it to operate in both low-voltage and high-voltage environments. Its quick switchover time of 50ns makes it suitable for switching and multiplexing applications.

The ADG5249FBRUZ-RL7 features a maximum differential input voltage range of ±2V. It is a low power-consuming device consumes only 550μA of quiescent current typically. With its low voltage operation, it can be operated from a single 3.0V power supply as well as dual supply. The device also features protection circuits designed to safeguard the device against ESD and EMC.

The working principle of ADG5249FBRUZ-RL7 is that the control logic level is used to select which one of the two inputs is connected to the output. When the control is low, the A input is connected to the output and the B input is not connected. When the control is high, the B input is connected to the output and the A input is not connected. The switches are protected with current limiting protection, Schottky diodes and ESD protection.

To sum up, ADG5249FBRUZ-RL7 is an ideal analog switch, multiplexer and demultiplexer for applications involving low impedance circuitry, buffering analogue signals, or providing isolation and protection from overvoltage and EMC interference. It features a low input voltage for signals, fast switching speeds, and low on-state resistance. It also features protection circuits designed to safeguard the device against ESD and EMC.
