**ADG1604BRUZ: A Comprehensive Technical Overview of Analog Devices' 4-Channel Multiplexer**

The **ADG1604BRUZ** from Analog Devices represents a high-performance, monolithic CMOS 4-channel analog multiplexer, engineered to provide exceptional signal integrity and reliability for a wide array of precision applications. This device is designed to switch one of four differential inputs to a common differential output, making it an indispensable component in data acquisition systems, medical instrumentation, and automated test equipment where signal routing accuracy is paramount.

At the core of its architecture, the **ADG1604BRUZ** operates on a **break-before-make switching action**, a critical feature that prevents momentary shorting between channels during transition, thereby safeguarding sensitive downstream components. Fabricated with an advanced CMOS process, the multiplexer boasts an impressively low on-resistance of just **2.5 Ω (typical)** and exhibits minimal flatness (0.5 Ω) across the entire signal range. This low and consistent resistance is vital for minimizing signal attenuation and distortion, especially when handling low-level analog voltages.

The device offers a broad **±5 V to ±22 V dual-supply or +8 V to +44 V single-supply operation**, providing designers with significant flexibility in system power design. Its **±15 V analog signal range** ensures compatibility with industrial-level signals. Furthermore, the ADG1604BRUZ features **TTL and CMOS-compatible digital inputs**, allowing for seamless interfacing with modern microcontrollers, FPGAs, and digital logic without requiring additional level-shifting circuitry.

A key performance metric for any multiplexer is its leakage current. The ADG1604BRUZ excels here with an ultra-low **leakage current of less than 100 pA at 25°C**, which is crucial for maintaining accuracy in high-impedance circuits and precision measurement systems. This is complemented by a fast switching speed, with **tON typically at 175 ns and tOFF at 145 ns**, enabling rapid channel selection in high-throughput systems.

Housed in a compact **24-lead TSSOP package**, the device is optimized for space-constrained PCB layouts. Its robust construction ensures excellent **ESD protection of 4 kV (HBM)**, enhancing system durability and long-term reliability in harsh environments.

**ICGOO**DFIND: The ADG1604BRUZ stands out as a superior solution for precision signal routing, offering an optimal blend of low on-resistance, high switching speed, wide voltage handling, and robust packaging. Its performance characteristics make it an ideal choice for designers who cannot compromise on signal fidelity and system reliability.
