**AD7863BRZ-10: A High-Speed, Low-Power, 4-Channel Simultaneous Sampling ADC**

In the realm of data acquisition systems, the ability to accurately capture multiple analog signals at the same instant is critical for applications such as polyphase motor control, sonar processing, and power quality monitoring. The **AD7863BRZ-10** from Analog Devices stands out as a premier solution, masterfully integrating **high-speed performance** with **exceptionally low power consumption** in a compact package.

This 14-bit analog-to-digital converter (ADC) is engineered around a successive approximation register (SAR) architecture, which is renowned for its precision and stability. Its defining feature is the **integrated quad sample-and-hold amplifier**, which enables true **simultaneous sampling** of four independent input channels. This ensures that the phase information between all inputs is preserved at the moment of conversion, a non-negotiable requirement for accurate analysis in three-phase systems and multi-axis motion control.

Operating with a **throughput of up to 500 kSPS**, the AD7863BRZ-10 delivers rapid conversion times without sacrificing accuracy. Despite this high speed, it maintains a remarkably low power dissipation, typically drawing just **30 mW** during normal operation. This combination makes it ideally suited for portable, battery-powered instruments and high-channel-density systems where power and space are at a premium.

The device offers exceptional ease of use. It features a streamlined parallel interface for seamless connection to modern microcontrollers and DSPs, and its operation is guaranteed over the industrial temperature range (-40°C to +85°C). The `-10` suffix denotes its ±10 V input range, making it directly compatible with a wide array of industrial-level signals without external attenuation.

**ICGOO**DFIND: The AD7863BRZ-10 is a benchmark **4-channel simultaneous sampling ADC** that successfully balances the often competing demands of **speed, power, and integration**. Its robust performance and versatile input ranges solidify its position as a go-to component for designers building high-fidelity, multi-channel data acquisition systems.
