**ADG513BNZ: A High-Performance, 4-Channel CMOS Multiplexer for Precision Signal Routing Applications**
In the realm of electronic design, the accurate routing of analog signals is a critical requirement for systems ranging from automated test equipment (ATE) and data acquisition (DAQ) systems to medical instrumentation and industrial control. The **ADG513BNZ from Analog Devices** stands out as a premier solution, engineered to meet the stringent demands of these precision applications. This 4-channel single-ended multiplexer integrates high performance, robustness, and integration into a compact package, establishing itself as a cornerstone component for complex signal routing tasks.
Constructed on an advanced **low-voltage CMOS process**, the ADG513BNZ is designed to handle both analog and digital signals with exceptional fidelity. It features four independently selectable channels, allowing a common output to be connected to one of four inputs, as determined by a simple 2-bit binary address. A key attribute of this device is its **low on-resistance (Ron) of just 2.5 Ω typical**, which remains exceptionally flat across the entire analog input range. This minimal and linear resistance is paramount, as it ensures negligible signal attenuation and distortion, preserving the integrity of even the most sensitive low-voltage signals.
The multiplexer operates over a wide **dual-supply range of ±5 V to ±20 V or a single-supply range of +8 V to +44 V**, offering designers tremendous flexibility in accommodating various system voltage levels. Furthermore, it boasts **break-before-make switching action**, a critical feature that prevents momentary shorting between input channels during switching, thereby protecting delicate source circuitry.
For precision applications, leakage currents and power consumption are vital metrics. The ADG513BNZ excels with its **ultra-low leakage currents of less than 100 pA** and a typical power consumption of a mere 3 μW. This makes it an ideal choice for battery-powered or portable equipment where minimizing power drain is essential. The device also includes TTL/CMOS-compatible digital inputs, ensuring easy interfacing with modern microcontrollers, FPGAs, and DSPs without requiring additional level-shifting circuitry.
Housed in a space-saving 16-lead SOIC_N package, the ADG513BNZ is built for reliability. It is characterized for extended industrial temperature ranges (-40°C to +85°C), ensuring stable operation in harsh environments. Its robust design offers **latch-up immunity under any circumstance**, a significant advantage for mission-critical systems where downtime is not an option.
**ICGOODFIND**: The ADG513BNZ is a superior 4-channel CMOS multiplexer that delivers a combination of low on-resistance, high accuracy, wide voltage range operation, and robust protection features. It is an indispensable component for engineers designing systems where **precision signal integrity** is non-negotiable.
