**ADG1409YCPZ-REEL7: A High-Performance 16-Channel Analog Multiplexer for Precision Signal Routing**

In the realm of modern electronic systems, the accurate routing of analog signals is a critical requirement across a wide range of applications, from automated test equipment (ATE) and data acquisition systems to medical instrumentation and communication infrastructure. The **ADG1409YCPZ-REEL7** from Analog Devices stands out as a premier solution, engineered to deliver exceptional performance and reliability for complex signal switching tasks.

This integrated circuit is a monolithic, complementary metal-oxide-semiconductor (CMOS) device featuring **16 independently selectable channels**. It operates as a single-pole, 16-throw (SP16T) switch, capable of connecting a common output to one of sixteen input sources. This architecture is indispensable in systems where multiple sensors or signal sources must be sequentially monitored or processed by a single, high-precision analog-to-digital converter (ADC) or amplifier, thereby reducing system size, cost, and complexity.

A defining characteristic of the ADG1409 is its **low on-resistance (Ron) of just 2.5 Ω**, which remains exceptionally flat across the entire analog input range. This low and linear resistance is paramount as it minimizes signal distortion and power loss, ensuring that the integrity of even the most delicate analog signals is preserved. Furthermore, the device boasts an impressive **on-resistance matching between channels of only 0.2 Ω**, guaranteeing consistent performance regardless of which path is selected. This level of precision is crucial for high-accuracy measurement systems where channel-to-channel variation must be negligible.

The multiplexer is designed to handle **bipolar analog signals up to ±15 V**, making it versatile for both single-supply and dual-supply operations. Its broad power supply range provides designers with significant flexibility in system architecture. The **break-before-make switching action** is a critical built-in feature that prevents momentary shorting between input channels during switching, thereby protecting sensitive source circuitry.

Packaged in a compact 32-lead LFCSP (Lead Frame Chip Scale Package), the ADG1409YCPZ-REEL7 is optimized for space-constrained applications. The `-REEL7` suffix indicates it is supplied on a 7-inch reel, making it compatible with high-speed automated assembly processes, which is essential for volume manufacturing. Its robust design ensures minimal charge injection and ultra-low leakage currents, which are vital parameters for maintaining accuracy in high-impedance circuits.

**ICGOOFind Conclusion:**

The ADG1409YCPZ-REEL7 establishes itself as an industry benchmark for precision analog multiplexing. Its combination of **ultra-low on-resistance, high channel count, and superb linearity** makes it an indispensable component for design engineers who cannot compromise on signal fidelity. It effectively simplifies system design while enhancing overall measurement accuracy and reliability.
