**AD7266BCPZ-REEL7: A 12-Bit, 3 MSPS Dual SAR ADC for Precision Measurement Systems**

In the realm of high-performance data acquisition, the ability to accurately capture and digitize analog signals is paramount. The **AD7266BCPZ-REEL7** from Analog Devices stands out as a premier solution, engineered to meet the rigorous demands of precision measurement systems. This integrated circuit is a **dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC)** capable of a impressive **3 million samples per second (MSPS)** throughput.

The core strength of the AD7266 lies in its **simultaneous sampling capability**. Both ADC channels can sample their respective input signals at the exact same instant, a critical feature for applications like phase-sensitive control in motor drives, power quality analysis, and multi-axis inertial measurement where maintaining the precise temporal relationship between channels is essential. This eliminates phase delays and provides a true snapshot of system conditions.

Architecturally, the device incorporates everything needed for a complete data acquisition path. Each channel is served by its own dedicated ADC, preceded by a **low noise, wide bandwidth track-and-hold amplifier**. This ensures accurate capture of fast-moving signals. Furthermore, the AD7266 includes an internal **2.5V reference** and a versatile serial interface, simplifying design-in and reducing the bill of materials and board space. The SPI/QSPI/MICROWIRE/DSP-compatible interface allows for easy connection to a wide range of microcontrollers and digital signal processors.

Performance is characterized by exceptional accuracy and dynamic range. With **12-bit resolution** and no missing codes, the converter guarantees precise linearity. Key specifications such as **low integral nonlinearity (INL)** and **differential nonlinearity (DNL)** contribute to its high DC accuracy, while its strong **signal-to-noise ratio (SNR)** ensures excellent performance in AC measurement scenarios.

Housed in a compact 32-lead LFCSP package, the AD7266BCPZ-REEL7 is designed for space-constrained environments. Its combination of speed, dual-channel simultaneity, and integrated features makes it an ideal choice for a vast array of applications, including industrial process control, medical instrumentation, high-speed data acquisition systems, and precision automated test equipment.

**ICGOOODFIND**: The AD7266BCPZ-REEL7 is a highly integrated, high-performance dual SAR ADC that delivers **simultaneous sampling, excellent DC precision, and AC performance** in a small form factor, making it a top-tier component for sophisticated measurement systems.
