**AD7616BSTZ: A 16-Channel, 16-Bit, Simultaneous Sampling SAR ADC for High-Precision Data Acquisition Systems**
In the realm of high-precision data acquisition, the ability to accurately capture multiple analog signals simultaneously is paramount. The **AD7616BSTZ** from Analog Devices stands as a pivotal solution, engineered to meet the rigorous demands of applications requiring high channel count, exceptional accuracy, and true simultaneous sampling. This 16-bit, 16-channel Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) integrates critical functionality into a single package, simplifying system design while delivering superior performance.
**Architectural Excellence and Key Features**
At the core of the AD7616BSTZ's capability is its **true simultaneous sampling architecture**. The device incorporates 16 individual sample-and-hold amplifiers on its input. This allows it to capture the voltage present on all 16 channels at exactly the same instant, a critical feature for multi-phase power control, condition monitoring, and instrumentation systems where phase relationship between signals is essential for accurate analysis.
The ADC achieves **16-bit resolution** without any missing codes, ensuring high linearity and providing the fine detail needed to resolve small changes in analog signals. It supports **bipolar input ranges of ±10 V, ±5 V, and ±2.5 V**, programmable on a per-channel basis. This flexibility allows it to interface directly with a wide variety of sensors and signal conditioning circuits without requiring external level-shifting components.
Further enhancing its integration, the AD7616BSTZ includes a **2.5 V internal reference** with low drift, which can be used internally or buffered for external use. It also features an on-chip digital filter for oversampling, which can improve resolution and reduce noise. Data output is facilitated through a parallel 16-bit or serial SPI interface, offering flexibility for connection to various processors, FPGAs, or microcontrollers.
**Performance for Demanding Environments**
The device is designed for robustness in challenging environments. It offers **high channel-to-channel isolation (>80 dB)** and excellent AC performance, including a high signal-to-noise ratio (SNR) of typically 90 dB. With a throughput rate of up to 1 MSPS for a single channel or 250 kSPS for all 16 channels, it provides ample speed for a vast array of industrial and instrumentation applications.
**Diverse Application Spectrum**
The combination of high channel count, simultaneous sampling, and robust performance makes the AD7616BSTZ ideal for a multitude of high-precision systems. Key applications include:
* **Power Line Monitoring and Protection Systems:** Precisely measuring voltages and currents in multi-phase power grids.
* **Industrial Automation and Control:** Simultaneously acquiring data from numerous sensors in PLCs and motor control centers.
* **Medical Imaging and Patient Monitoring:** Capturing data from multi-element sensors with precise timing.
* **Test and Measurement Equipment:** Serving as the core of high-performance data acquisition cards and oscilloscopes.
