**The ADG513BR: A High-Performance, 4-Channel CMOS Multiplexer for Precision Signal Routing**

In the realm of electronic design, the accurate and reliable routing of analog signals is a critical function across a vast array of applications, from automated test equipment to data acquisition systems. The **ADG513BR**, a monolithic CMOS device, stands out as a premier solution, offering designers a robust and highly integrated quad single-pole/single-throw (SPST) switch for precision signal management.

This multiplexer integrates four independent switches on a single chip, providing exceptional flexibility for routing signals. Each switch features **low on-resistance (typically 35 Ω)** and remarkably flat on-resistance performance across the input signal range. This characteristic is paramount as it minimizes signal distortion and ensures linearity, preserving the integrity of even the most sensitive analog signals. The device operates from a single supply ranging from +3 V to +15 V or from dual supplies of ±3 V to ±8 V, making it compatible with a wide spectrum of system-level voltages.

A key performance metric for any analog switch is its ability to isolate signals when in the off state. The ADG513BR excels here with its **exceptionally low leakage currents**, typically just a few nanoamperes. This high off-isolation prevents signal bleed-through, a crucial feature in precision measurement and multiplexing applications where crosstalk can severely degrade system accuracy.

Furthermore, the device is engineered for fast switching speeds and break-before-make switching action. This design prevents momentary shorting between channels during the switching process, thereby protecting downstream circuitry. The TTL/CMOS-compatible digital inputs simplify interface with modern microcontrollers, FPGAs, and digital logic, allowing for straightforward control of the signal paths.

The **ADG513BR is housed in a compact 16-lead SOIC package**, which is ideal for space-constrained PCB designs. Its construction using advanced CMOS technology ensures **very low power consumption**, making it suitable for portable and battery-powered instruments. The combination of high performance, integration, and reliability makes the ADG513BR an indispensable component for designers tasked with building precise and efficient electronic systems.

**ICGOODFIND:** The ADG513BR is a superior choice for high-performance signal routing, offering an optimal blend of low on-resistance, high channel isolation, wide voltage operation, and robust integration in a space-saving package, making it ideal for precision applications in test, measurement, and data acquisition.
