**ADG513BN: 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 across a vast array of applications, from automated test equipment (ATE) and data acquisition systems to medical instrumentation and industrial control. The **ADG513BN**, a monolithic CMOS device, stands out as a premier solution, engineered to deliver exceptional performance and reliability for these demanding precision signal routing tasks.

This integrated circuit is a **single-pole, quadruple-throw (4:1) multiplexer**, meaning it can select one of four independent analog input signals and connect it to a common output channel. The selection is digitally controlled via two binary address lines (A0, A1) and an enable pin, allowing for simple and seamless integration with microcontrollers, FPGAs, and digital signal processors. The core strength of the ADG513BN lies in its **low on-resistance (35 Ω typical)** and remarkably **flat on-resistance across the entire signal range**. This characteristic is paramount as it minimizes signal distortion and errors, ensuring that the integrity of the passed analog signal is preserved, whether it is a voltage or a current.

Furthermore, the device is designed for **break-before-make switching action**, a crucial feature that prevents momentary shorting between different input channels during switching transitions. This protects both the signal sources and the multiplexer itself from potential damage. Built on an advanced CMOS process, the ADG513BN also boasts **very low power consumption and high switching speeds**, making it an ideal choice for both portable, battery-operated devices and high-speed systems.

The operational flexibility of the ADG513BN is enhanced by its wide dual-supply (±5 V to ±20 V) or single-supply (+5 V to +40 V) operation. This broad supply range allows it to handle a wide spectrum of analog signal levels. Its architecture ensures **ultra-low leakage currents**, which is a critical parameter for maintaining accuracy in high-impedance circuits and precision measurement applications.

**ICGOOODFIND**: The ADG513BN establishes itself as a superior and robust 4-channel multiplexer, offering designers an optimal blend of low on-resistance, high linearity, and versatile power supply options. It is an indispensable component for any system where precision, accuracy, and signal fidelity are non-negotiable.
