Introduction

The ADG2128YCPZ-REEL7 (or ADG2128 for short) is a high performance, dual 4:1 multiplexer with a special purpose analog switch arranged in a compact package. It is a member of the Analog Devices portfolio of multiplexers, selectors and analog switches that provide digital control over signal routing, enabling an IC to select the desired signal before routing it to its destination.

The ADG2128 is ideal for use in applications that require high-speed signal multiplexing with low on-resistance, such as radio communication systems, test and measurement systems, and automotive applications. It also has built-in ESD protection to prevent damage in case of an ESD event.

Applications

The ADG2128 is designed for use in a variety of applications, including:

• Signal conditioners for test and measurement systems,
• Digital signal processing (DSP) systems,
• Radio communications systems,
• Medical imaging systems,
• Motor control applications,
• Power line conditioning,
• Automotive applications.

The ADG2128 can be used in a wide range of applications, such as signal routing and signal switching.

Features

The ADG2128YCPZ-REEL7 features a variety of features, including:

• Low on-resistance (R_ON) of 7 Ω (typical).
• Low on Resistance (R_ON) Flatness of 0.5 Ω.
• Isolation Voltage (V_ISO) of ±5300 V.
• Low Charge Injection of 25 pC (typical).
• Fast settling time of 20 ns (typical).
• Wide t_OFF range of 20 μs to 3 ms.
• Compact SOIC-8 package.

The ADG2128YCPZ-REEL7 is also designed to operate from a single supply voltage between 3.3 V and 5.5 V and can handle input signals with a peak to peak range of ±4 V.

Working Principle

The ADG2128YCPZ-REEL7 works by allowing two separate signals to be multiplexed into one. When the device is activated, the two channels are merged into one, allowing the user to select which signal is routed to its destination.

The ADG2128YCPZ-REEL7 operates by making use of an external voltage source. This voltage source is used to control the electric current that flows through the device, thus allowing the user to control the on state resistance (R_ON) of the multiplexer.

The ADG2128YCPZ-REEL7 also features a charge injection limiter, which prevents any unwanted current to flow when the device is activated, thus reducing the distortion of the input signal.

Conclusion

The ADG2128YCPZ-REEL7 is a high performance, dual 4:1 multiplexer with a special purpose analog switch. Its low R_ON and fast settling time make it an ideal solution for applications that require high-speed signal multiplexing. Its features also make it an attractive solution for a wide range of applications, such as test and measurement systems, medical imaging systems, power line conditioning, and automotive applications.
