**AD4695BCPZ: A 16-Bit, 16-Channel Precision SAR ADC for High-Accuracy Data Acquisition Systems**

In the realm of high-precision data acquisition, the ability to accurately digitize multiple analog signals is paramount. The **AD4695BCPZ** from Analog Devices stands as a pinnacle component in this space, engineered to deliver exceptional performance in demanding measurement and control applications. This 16-bit, 16-channel successive approximation register (SAR) analog-to-digital converter (ADC) integrates critical features that simplify system design while achieving top-tier accuracy, speed, and power efficiency.

At the core of the AD4695BCPZ is a highly stable **16-bit SAR ADC core** that guarantees outstanding linearity, featuring **±0.5 LSB INL (max)** and **±0.4 LSB DNL (max)**. This ensures no missing codes and provides the precise, reliable data essential for systems such as automated test equipment (ATE), industrial process control, and medical instrumentation. The device supports a versatile **16-channel single-ended or 8-channel differential** multiplexed input front-end, offering unparalleled flexibility in interfacing with a wide array of sensors and signal sources across multiple domains.

A key advantage of the AD4695 is its **high throughput capability**, achieving **1 MS/s per channel** when sequentially scanning all inputs. This speed is complemented by an ultra-low power dissipation architecture, consuming a mere **4.5 mW per channel at 1 MS/s**, making it suitable for both power-sensitive and high-density systems. The integrated functionality extends beyond the ADC core; it includes a **programmable input buffer** for high-impedance sensor interfacing, a **low-drift 2.5 V internal reference** (with an option for an external reference), and a versatile serial peripheral interface (SPI). These integrated features drastically reduce the bill of materials (BOM), minimize board space, and alleviate the design complexity typically associated with achieving such high levels of performance.

Furthermore, the device is designed for robustness in electrically noisy environments. Its **high common-mode rejection ratio (CMRR)** enables excellent performance even in the presence of significant noise. Housed in a compact, 64-lead LFCSP package, the AD4695BCPZ is built for space-constrained applications requiring maximum channel density and reliability.

**ICGOODFIND**: The AD4695BCPZ is a highly integrated, precision data acquisition solution that sets a new benchmark for multi-channel systems. Its combination of **exceptional 16-bit accuracy**, **high channel count**, **flexible input configuration**, and **remarkable power efficiency** eliminates traditional design trade-offs, providing engineers with a single-component answer for building next-generation, high-accuracy data acquisition systems.
