**High-Performance 16:1 Analog Multiplexer IC: ADG1607BRUZ-REEL7 Datasheet and Application Guide**
In the realm of precision signal routing, the **ADG1607BRUZ-REEL7** from Analog Devices stands out as a premier high-performance, single-ended 16-channel analog multiplexer. Engineered for a wide array of demanding applications, this IC is designed to switch one of sixteen inputs to a common output with exceptional accuracy and minimal signal distortion. This article delves into the key specifications from its datasheet and provides a practical application guide for system designers.
A core strength of the ADG1607 is its **low on-resistance of just 2.5 Ω**, which remains exceptionally flat across the entire analog input range. This characteristic is paramount as it minimizes insertion loss and reduces distortion of the switched signal, ensuring signal integrity is preserved from source to destination. The device operates on a **single-supply range from 3.0 V to 5.5 V**, making it perfectly suited for both 3.3 V and 5 V systems, including those powered by batteries. Furthermore, it offers **-3 dB signal bandwidth of 105 MHz**, enabling it to handle high-frequency signals effectively.
The ADG1607 features **break-before-make switching action**, a critical safety function that prevents two input channels from being shorted together during the switching transition. This protects both the signal sources and the multiplexer itself. The device is controlled via a 4-bit binary address line (A0, A1, A2, A3) and an enable pin, offering straightforward digital interfacing with microcontrollers, FPGAs, and DSPs.

The ADG1607’s combination of high performance and versatility makes it ideal for numerous systems:
1. **Data Acquisition Systems (DAQ):** It is perfect for **multiplexing multiple analog sensor inputs** (e.g., temperature, pressure, strain gauges) into a single, high-precision analog-to-digital converter (ADC), significantly reducing system size and cost.
2. **Automated Test Equipment (ATE):** Its high channel count and fast switching speed allow for efficient routing of test signals between instruments and the device under test (DUT).
3. **Communication Systems:** The high bandwidth supports signal routing in video switching and RF applications.
4. **Battery-Powered Instruments:** The low power consumption and single-supply operation are ideal for **portable and handheld medical devices or environmental monitors**.
5. **Industrial Control Systems:** It can be used to monitor various process control points, sending data back to a central processor.
When designing with the ADG1607, careful attention should be paid to PCB layout. Bypass capacitors (typically 0.1 µF) should be placed as close as possible to the supply pins (VDD and GND) to ensure stable operation. For applications involving high-precision DC signals, mitigating the effects of leakage current and charge injection through proper supply decoupling and driver selection is recommended.
**ICGOOODFIND:** The ADG1607BRUZ-REEL7 is a robust and highly integrated solution for complex analog signal routing challenges. Its outstanding combination of **low on-resistance, high bandwidth, and single-supply operation** makes it an indispensable component for designers aiming to achieve high channel density and superior signal fidelity in modern electronic systems.
