**ADG2128YCPZ-REEL7: A Comprehensive Overview of Analog Devices' CMOS 8 x 12 Crosspoint Switch**
The **ADG2128YCPZ-REEL7** is a high-performance, monolithic **CMOS 8 x 12 crosspoint switch** from Analog Devices, designed to address complex signal routing challenges in a wide array of applications. This device integrates 96 independently programmable switches on a single chip, allowing any of its 8 input channels to be connected to any of its 12 output channels with exceptional flexibility. Its architecture is engineered to provide a **non-blocking matrix**, ensuring that all possible input-to-output connections can be made simultaneously without interference.
Fabricated on an advanced CMOS process, the ADG2128 offers **low power consumption** and operates from a single **+3.3 V to +3.6 V supply**, making it ideal for portable and battery-powered equipment. A key feature is its **on-chip latches** with **Schmitt-trigger inputs**, which facilitate easy interfacing with microprocessors and digital systems for simple control and programming via a serial peripheral interface (SPI). This programmability allows for dynamic reconfiguration of signal paths during operation, which is crucial for systems requiring adaptive routing, such as automated test equipment (ATE), medical instrumentation, and communication infrastructure.
The switch boasts impressive analog signal handling capabilities, supporting both **bipolar and unipolar signals** within the supply rails. It features a broad analog voltage range and offers **low on-resistance (Ron)** of typically 60 Ω, with excellent flatness and matching across all channels. This ensures minimal signal distortion and insertion loss, which is critical for maintaining signal integrity in high-precision audio and video routing, as well as in data acquisition systems. Furthermore, the device exhibits very low quiescent current, enhancing its suitability for power-sensitive designs.
Housed in a compact, space-saving **7x7 mm 56-lead LFCSP package**, the ADG2128YCPZ-REEL7 is provided on a 13-inch reel, making it compatible with high-volume automated assembly processes. Its robust construction is designed to meet the demands of industrial environments, with an extended operating temperature range.
**ICGOODFIND:** The ADG2128YCPZ-REEL7 stands out as a highly integrated, flexible, and efficient solution for complex signal routing matrices. Its combination of a large switch array, low power consumption, simple digital control, and excellent analog performance makes it a superior choice for designers in ATE, medical imaging, and audio-video switching systems.
