**ADG4612BCPZ-REEL7: High-Performance, Low-Leakage Quad SPST Switch for Precision Signal Routing Applications**

In the realm of precision electronics, the accurate routing of sensitive analog and digital signals is paramount. The **ADG4612BCPZ-REEL7** from Analog Devices stands out as a premier solution, engineered to meet the stringent demands of high-accuracy test and measurement equipment, data acquisition systems, and medical instrumentation. This integrated circuit is a **monolithic quad, single-pole/single-throw (SPST) switch** that sets a new benchmark for performance in signal path management.

At the core of the ADG4612's design is its **ultra-low leakage current**, typically as low as 100 pA at 25°C. This exceptional characteristic is critical for applications where even minute currents can introduce significant errors, ensuring that the integrity of the signal is preserved from source to destination. This is complemented by its low on-resistance (RON) of just 2.5 Ω, which remains exceptionally flat across the input signal range. This **low and flat on-resistance** minimizes distortion and power loss, guaranteeing that the signal passes through the switch with minimal degradation.

The device operates over a wide **bipolar power supply range from ±5 V to ±22 V**, or a single-supply range of 8 V to 44 V. This remarkable flexibility allows designers to integrate the switch into a vast array of systems, from high-voltage industrial controls to portable, battery-powered devices. Furthermore, the ADG4612BCPZ-REEL7 features **break-before-make switching action**, a crucial safety mechanism that prevents momentary shorting between channels during switching transitions, thereby protecting both the switch and the downstream circuitry.

Housed in a compact, space-saving 16-lead LFCSP package, the device is ideal for high-density board layouts. Its **TTL/CMOS-compatible digital inputs** simplify interface logic with modern microcontrollers and FPGAs, streamlining system design. The combination of high performance, robust construction, and design flexibility makes the ADG4612 an indispensable component for engineers tasked with routing precision signals in the most challenging environments.

**ICGOOODFIND:** The ADG4612BCPZ-REEL7 is a superior quad SPST analog switch that delivers **unmatched signal fidelity** through its ultra-low leakage and low, flat on-resistance. Its versatile power supply range and robust protection features make it an essential building block for precision signal routing in mission-critical applications.
