**AD7863BRZ-3: A High-Performance, 14-Bit Simultaneous Sampling ADC for Precision Measurement Systems**

In the realm of precision measurement and data acquisition systems, the ability to accurately capture multiple analog signals at the same instant is paramount. The **AD7863BRZ-3** from Analog Devices stands as a pivotal solution, engineered to meet the rigorous demands of high-performance applications. This integrated circuit is a **14-bit, simultaneous sampling analog-to-digital converter (ADC)** that excels in environments where timing correlation between channels is critical.

The core architecture of the AD7863BRZ-3 incorporates four distinct ADC channels, each capable of digitizing analog inputs at a resolution of 14 bits. Its defining feature is **true simultaneous sampling**, achieved through dedicated track-and-hold amplifiers on each input channel. This ensures that all four channels are sampled at precisely the same moment, preserving the phase relationship between signals. This capability is indispensable in multi-phase power control systems, polyphase motor control, and high-end instrumentation where analyzing the interaction between signals is essential.

Performance is further highlighted by its impressive throughput. The device boasts a fast conversion time of **1.65 µs per channel**, enabling a high aggregate sampling rate across all inputs. It operates with a single +5 V supply, simplifying power management design, and features a flexible analog input range, including standard ±10 V and ±5 V options, making it versatile for various industrial voltage levels.

A significant advantage of the AD7863BRZ-3 is its **low power consumption**, typically drawing just 100 mW, which is a critical factor in power-sensitive or portable measurement equipment. Furthermore, it integrates robust digital interfaces for seamless communication with microcontrollers and digital signal processors (DSPs), streamlining system integration.

The device is offered in a compact SOIC package, providing a balance between board space efficiency and thermal performance. Its specified operating temperature range ensures reliability in industrial environments.

**ICGOOFind:** The AD7863BRZ-3 is an exceptional simultaneous sampling ADC that delivers high accuracy, channel synchronization, and system integration capabilities. It is an optimal choice for designers developing advanced measurement systems in aerospace, industrial automation, and energy management, where precision and timing fidelity are non-negotiable.
