Release date:2025-09-12 Number of clicks:193

**The AD9248BCPZ-65 represents a pinnacle of performance and integration in the realm of analog-to-digital conversion.** As a **14-bit, 65 MSPS dual-channel ADC**, it is engineered to meet the demanding requirements of modern high-performance signal acquisition systems, including communications infrastructure, medical imaging, and advanced instrumentation. This device combines high dynamic performance with low power consumption, making it an optimal solution for space-constrained and power-sensitive applications.

A key strength of the AD9248BCPZ-65 lies in its **dual-channel architecture**, which allows for the simultaneous sampling of two independent analog input signals. Each channel operates at up to 65 million samples per second (MSPS) while maintaining exceptional fidelity. This capability is critical for applications like I/Q demodulation in software-defined radios (SDRs) or complex data acquisition systems requiring precise phase matching between channels. The device ensures **excellent channel-to-channel isolation**, minimizing crosstalk and preserving signal integrity across both inputs.

The ADC's core is built on a sophisticated pipeline architecture, delivering **outstanding dynamic performance**. It typically achieves a signal-to-noise ratio (SNR) of greater than 75 dB and a spurious-free dynamic range (SFDR) of 90 dB at intermediate frequencies, ensuring that even small signals are digitized with high accuracy amidst larger ones. This high resolution and speed make it ideal for digitizing wide bandwidth signals with complex modulation schemes.

Furthermore, the AD9248BCPZ-65 is designed for ease of integration. It features a **flexible digital output interface** compatible with 1.8V logic, simplifying connections to modern FPGAs and ASICs. Its integrated input buffer simplifies the front-end design by providing a high-impedance input, reducing the need for external driving circuitry. Housed in a compact, 32-lead LFCSP (Lead Frame Chip Scale Package), the device is suited for dense PCB layouts. Operating on a single 1.8V supply and consuming a remarkably low amount of power per channel, it addresses the critical need for performance without excessive heat dissipation.

**ICGOO**D**FIND**: The AD9248BCPZ-65 stands out as a superior solution for designers seeking a combination of high speed, resolution, and dual-channel integration. Its blend of **exceptional dynamic performance**, **low power consumption**, and **compact packaging** makes it a cornerstone component for next-generation signal acquisition systems where accuracy, size, and efficiency are paramount.
