**ADG888YRUZ: A Comprehensive Technical Overview of Analog Devices' Low-Voltage CMOS Switch**
In the realm of precision signal routing and system design, the performance of analog switches is paramount. The **ADG888YRUZ from Analog Devices** stands as a quintessential example of a highly integrated, low-voltage, dual SPDT (Single Pole, Double Throw) CMOS switch engineered for a wide array of applications. This device exemplifies the critical balance between **low on-resistance, minimal power consumption, and high switching speed**, making it an ideal component for portable, battery-operated, and space-constrained systems.
**Core Architecture and Functionality**
The ADG888YRUZ integrates two independently selectable single-pole, double-throw (SPDT) switches. This configuration allows each switch to connect a common input to one of two outputs, providing exceptional flexibility in routing analog signals. Fabricated on an advanced CMOS process, the switch is designed to operate from a single supply voltage ranging from **1.8 V to 5.5 V**, making it directly compatible with low-voltage microcontrollers, FPGAs, and modern digital systems. Its symmetric design ensures that either source or drain terminal can be used as an input or output, simplifying PCB layout and system design.
**Key Performance Characteristics**
A defining feature of the ADG888YRUZ is its remarkably **low on-resistance (Ron)**, which is typically 0.5 Ω when operating with a 5 V supply. Even at a reduced 1.8 V supply, Ron remains a low 1.5 Ω. This flatness and low value are crucial as they minimize signal distortion and voltage error, especially when switching critical analog signals or higher currents. The device boasts an ultra-low power consumption, drawing less than 0.01 μA of supply current, which is virtually negligible for most battery-life calculations.
Furthermore, the switch offers **excellent bandwidth characteristics**, supporting signals beyond 200 MHz. Its fast switching times, with tON typically at 20 ns and tOFF at 10 ns, ensure that it can handle rapid multiplexing tasks in data acquisition systems and video routing. The ADG888YRUZ also features **break-before-make switching action**, a critical safety function that prevents momentary shorting between channels during the switching transition.
**Application Spectrum**
The combination of its electrical characteristics opens the door to numerous applications. It is perfectly suited for:
* **Portable and Battery-Powered Equipment:** Audio and video signal routing, USB switching, and power management in smartphones, tablets, and medical monitors.
* **Communication Systems:** Signal routing in RF modules and wireless infrastructure.
* **Automated Test Equipment (ATE) and Data Acquisition Systems:** Multiplexing analog signals from sensors to an ADC with minimal introduced error.
* **Consumer Electronics:** Function switching in set-top boxes, laptops, and digital cameras.
**Package and Reliability**
Housed in a compact, space-saving **16-lead TSSOP package**, the ADG888YRUZ is designed for high-density board layouts. Analog Devices ensures high reliability with **latch-up immunity** and ESD protection on all pins, safeguarding the device and the system from electrostatic discharge events during handling and operation.
**ICGOODFIND**
The ADG888YRUZ is a superior choice for designers seeking a high-performance, low-voltage analog switch. Its exceptional combination of **ultra-low on-resistance, wide bandwidth, and minuscule power consumption** in a tiny form factor makes it an indispensable component for optimizing signal integrity and efficiency in modern electronic designs.
