Analog switches, multiplexers, and demultiplexers are widely used in electronic circuits involving signals that need to be consistently routed from one point of a system to another. The ADG774BRQ-REEL7, an ultra-high speed CMOS analog switch, is an ideal device for these applications. The operation of this particular device is based on exponentially weighted linear resistors, with excellent digital control and an inverted salinity feature.

Features of ADG774BRQ-REEL7

The ADG774BRQ-REEL7 contains two 4-channel, 1-of-4, 40 V pins for CMOS switching applications. It operates from a single 3.0 V to 5.5 V supply and features a maximum on-resistance of 0.6Ω to 200Ω, an off-isolation of up to 80 dB, and a ripple rejection of up to 80 dB in attenuation. In addition, this device is characterized by excellent temperature stability over a wide temperature range and ESD protection levels of up to 25 kV HBM.

Application Field of ADG774BRQ-REEL7

The ADG774BRQ-REEL7 is designed for use in digital/analog interface and signal routing applications, such as multiplexing/demultiplexing, routing, and testing of low-speed signals. It can be used in a variety of applications, such as industrial automation, instrumentation, and digital measurement systems. Additionally, this device is well suited for automated testing equipment and amplifier protection applications.

Working Principle of ADG774BRQ-REEL7

The ADG774BRQ-REEL7 uses a unique circuit architecture with exponentially weighted linear resistors to provide superior performance in low-voltage, high-current environments. It works by having two switching elements, or contacts, which act together to route or switch analog and digital signals. The signals can be changed using the on-chip digital control inputs, and the device features an inverted polarity feature, allowing the device to be configured as either a normally open, or normally closed switch. When the switch is turned on, the contacts are either connected or disconnected, depending on the control inputs. When the switch is turned off, both contacts remain disconnected and the device is said to be in a non-conducting, or high-impedance state. This allows for the analog and digital signals to be routed to the desired location.

Conclusion

The ADG774BRQ-REEL7 is an ideal device for applications such as digital/analog interface and signal routing. It operates from a single 3.0 V to 5.5 V supply and features excellent performance characteristics, including maximum on-resistance of 0.6Ω to 200Ω, an off-isolation of up to 80 dB, and a ripple rejection of up to 80 dB in attenuation. This device is well suited for automated testing equipment and amplifier protection applications, and should be taken into consideration for any signal routing and control application.
