**AD7890ANZ-10: A 10-Bit, 28 MSPS Low Power Sampling ADC**

In the realm of data acquisition and signal processing, the need for high-speed analog-to-digital conversion with minimal power consumption is paramount. The **AD7890ANZ-10** from Analog Devices stands as a pivotal solution, engineered to deliver **10-bit resolution** at a remarkable **28 Mega Samples Per Second (MSPS)** while maintaining exceptionally low power dissipation. This combination of speed and efficiency makes it an ideal candidate for a wide array of demanding applications, from communications infrastructure to portable instrumentation.

At the heart of the AD7890ANZ-10 is a sophisticated sampling architecture that ensures accurate digitization of fast-moving analog signals. The converter utilizes a **pipelined conversion technique**, which allows it to achieve its high throughput rate with a minimal latency of just a few clock cycles. This feature is critical for real-time systems where timing is crucial. The device accepts a full-scale analog input range, typically configurable, and provides straight binary digital output, simplifying interface logic with downstream processors like FPGAs or DSPs.

A defining characteristic of this ADC is its **impressive power efficiency**. Operating from a single +5V supply, the AD7890ANZ-10 consumes a mere 90 mW (milliwatts) of power during active operation. Furthermore, it incorporates a power-down mode, reducing consumption to just a few microwatts when not in use. This is a vital attribute for **battery-powered and portable equipment**, where extending operational life is a primary design constraint. The low power design also minimizes self-heating, which contributes to the overall stability and reliability of the conversion results.

Beyond speed and power, the AD7890ANZ-10 is designed for signal integrity. It features a high-performance onboard sample-and-hold amplifier and a dedicated voltage reference, ensuring consistent accuracy. The device boasts excellent dynamic performance, including low **Signal-to-Noise and Distortion Ratio (SINAD)** and high **Spurious-Free Dynamic Range (SFDR)**, which are essential for discerning subtle details in complex waveforms, particularly in imaging and software-defined radio systems.

Housed in a compact 24-pin PDIP or SOIC package, the AD7890ANZ-10 offers a robust and space-saving solution for system designers. Its combination of **high-speed operation**, **low power consumption**, and **integrated features** provides a superior performance-to-power ratio, streamlining design complexity and reducing the total component count on the board.

**ICGOODFIND:** The AD7890ANZ-10 is a quintessential high-speed ADC that masterfully balances the often conflicting demands of speed, accuracy, and power consumption. It is a powerful enabler for next-generation applications in medical imaging, wireless communications, and high-speed data acquisition systems.
