The ADG802BRMZ-REEL7 from Analog Devices is a high-speed, single-pole double-throw (SPDT) switch with low on-resistance. It is designed for use as an analog switch, multiplexer, or demultiplexer. This device is suitable for a wide range of applications, including signal routing and signal switching in audio, automotive, industrial, and communications systems.

Applications

The ADG802BRMZ-REEL7 is a low cost, low power switch with a maximum on-resistance of just 0.8Ω. It is suitable for use as an analog switch, multiplexer, or demultiplexer in a wide range of applications, including signal routing, signal switching, and data routing in communications systems. It is particularly suitable for use as an analog switch for audio systems and telecommunications systems. Additionally, it can be used for DC and low frequency (up to 5MHz) signal switching in automotive, industrial, medical, and avionics systems.

Advantages

The ADG802BRMZ-REEL7 offers a number of advantages when compared to other switches in its class. It is a high-bandwidth switch with a maximum switching speed of 1ns. It has very low on-resistance and RON flatness. It also has low power consumption and a wide operating temperature range.

Working Principle

The working principle of the ADG802BRMZ-REEL7 switch is based on the Buckley switch concept. It consists of a single n-channel JFET switch and a single n-channel source voltage generator. The FET switch is driven by the logic signal controlled from the source voltage generator. When the logic signal is high, the FET switch is turned on and the source voltage drives the FET gate. The resulting drain current is then used to drive the connected load. When the logic signal is low, the FET switch is turned off and the load is disconnected from the source.

Conclusion

The ADG802BRMZ-REEL7 is a high-speed, low-power, low-cost switch. It is suitable for use as an analog switch, multiplexer, or demultiplexer in a wide range of applications. It has a low on-resistance and a wide operating temperature range. The working principle of the device is based on a Buckley switch concept, using an n-channel JFET switch and a source voltage generator.
