AD9248BST-40: 14-Bit, 40 MSPS, Dual Analog-to-Digital Converter

The AD9248BST-40 is a high-performance, dual-channel analog-to-digital converter (ADC) from Analog Devices Inc., designed to bridge the gap between the analog and digital worlds in your electronic applications. This ADC is capable of converting analog input signals into 14-bit digital data at a sample rate of up to 40 megasamples per second (MSPS).

With its dual ADC cores, the AD9248BST-40 offers a flexible and efficient solution for applications requiring high-speed data acquisition, such as medical imaging, communications, and instrumentation. The device features an on-chip voltage reference and sample-and-hold circuitry, which simplifies system design and reduces external component count.

The AD9248BST-40 operates with a single 3.3V supply, minimizing power consumption and making it suitable for power-sensitive applications. Additionally, it includes various digital features such as an adjustable digital output clock, data alignment, and digital test pattern generation, which aid in system-level calibration and diagnostics.

Key features of the AD9248BST-40 include:

• 14-bit resolution with no missing codes
• 40 MSPS per channel sample rate
• Low power consumption (455 mW at 40 MSPS)
• Single 3.3 V supply operation
• Internal or external reference
• Flexible output modes including twos complement or offset binary
• SNR (signal-to-noise ratio) of 72.7 dBFS at 70 MHz
• Differential inputs with 700 MHz full power bandwidth

The AD9248BST-40 is available in a space-saving 64-lead LQFP (low-profile quad flat package), which is ideal for compact designs. Its robust design and advanced features make it an excellent choice for engineers looking to implement high-speed, accurate data conversion in their next project.
