ADG621BRMZ-REEL

The ADG621BRMZ-REEL is a sample/hold analog switch comprising four SPST (single-pole, single-throw) switches, controlled via an all-digital CMOS process. This chip is ideal for applications in the interface, analog switches, multiplexers, demultiplexers fields, where a high speed, low-power analog switch is needed. This application note describes the ADG621BRMZ-REEL’s operating principles and explains how to use the chip for various applications.

The ADG621BRMZ-REEL is a low-noise, low-power, low-voltage CMOS device, suitable for applications operating at voltage levels up to 6V. It is a 4-channel analog switch that is controlled via a 3-wire digital interface. The on-chip digital logic that controls the switches is highly optimized, allowing for fast switching of the switches without any noticeable increase in power consumption.

One of the most important features of the ADG621BRMZ-REEL is its ability to offer very low leakage current between its switches. This is achieved by using a special “partial switching” mode, which eliminates the need for ground paths between the channels, thus reducing the leakage current to almost zero. The fact that the leakage current is so low also makes the chip ideal for data converters and other precision applications, as it allows for very accurate measurements to be taken.

The ADG621BRMZ-REEL also has an enable pin, which can be used to enable or disable the chip. This feature is extremely useful in systems where a part of the system needs to be powered down or disabled temporarily.

The ADG621BRMZ-REEL also has a built-in internal clock, which can be used to provide timing and synchronization signals to the chip. This clock is used to control the switch timing, and to ensure that the switching between the channels is done in a fast and accurate manner.

The ADG621BRMZ-REEL is ideal for use in multiplexers, demultiplexers, and other types of digital signal processing circuits where a fast, low-power switch is needed. It is also suitable for video and audio switches, as it is capable of handling signal levels up to 6V. The combination of its low power consumption, low noise, and low voltage features make it an optimal choice for many applications.

The ADG621BRMZ-REEL can also be used for signal routing. Its low-impedance design allows it to route signals with minimum signal degradation and crosstalk. It is also ideal for applications that require a large number of signals to be routed quickly and accurately.

In summary, the ADG621BRMZ-REEL is a powerful, low-power analog switch, which is ideal for applications in the interface, analog switches, multiplexers, demultiplexers fields. Its low-noise, low-power, and low-voltage features make it ideal for a wide range of applications, from data converters to video and audio switches. Its built-in internal clock allows it to provide highly accurate switch timing, making it an ideal choice for signal routing and other precision applications.
