**AD9258BCPZ-105: A 105 MSPS, 14-Bit Octal ADC for High-Performance Multichannel Systems**
In the realm of high-speed data acquisition, the demand for **simultaneous multichannel signal processing** is rapidly increasing across applications such as medical imaging, phased-array radar, and wireless communications. The AD9258BCPZ-105 stands out as a premier solution, engineered to meet these stringent requirements by integrating eight high-performance analog-to-digital converters (ADCs) into a single package. This device not only simplifies system design but also delivers exceptional performance where it matters most.
Operating at **105 Million Samples Per Second (MSPS)** with 14-bit resolution per channel, this octal ADC captures fine-grained details of fast-changing signals with remarkable accuracy. Each channel features its own dedicated sample-and-hold amplifier, ensuring true simultaneous sampling—a critical capability for applications requiring precise phase coherence across multiple inputs. The AD9258BCPZ-105 is built on a cutting-edge CMOS process, which enables its high integration while maintaining low power dissipation of just 100 mW per channel. This balance of **high speed and low power consumption** makes it ideal for dense, multichannel systems where thermal management and power budgets are key concerns.
A major advantage of this ADC is its **highly integrated signal chain**. It includes programmable input buffers, which simplify front-end design by providing a high-impedance input and eliminating the need for external drive components in many cases. Additionally, it incorporates a digital down-converter (DDC) block in each channel, featuring a numerically controlled oscillator (NCO) and decimation filters. This allows for flexible frequency planning and reduces the data rate to the downstream processor, alleviating the burden on FPGAs or ASICs.
The device also excels in dynamic performance. It achieves a **typical signal-to-noise ratio (SNR) of 72.5 dB** and a spurious-free dynamic range (SFDR) of 88 dB at 170 MHz input frequency, ensuring clean and reliable data conversion even in the presence of high-frequency inputs. Its serialized LVDS outputs further enhance system integration by reducing the number of interface lines, simplifying PCB layout, and minimizing noise.
Housed in a compact, 10 mm x 10 mm, 88-lead LFCSP package, the AD9258BCPZ-105 is designed for space-constrained environments. Its robust architecture is supported by a wealth of development resources, including evaluation boards and software, to accelerate design cycles and ensure first-pass success.
**ICGOODFIND Summary**: The AD9258BCPZ-105 is a **highly integrated, low-power octal ADC** that sets a new benchmark for performance in multichannel systems. Its combination of simultaneous sampling, excellent dynamic range, and on-chip signal processing features provides system designers with a powerful, single-chip solution that reduces complexity, saves board space, and accelerates time to market for the most demanding applications.
