LTC2249IUH - High-Speed ADC from Linear Technology

The LTC2249IUH is a cutting-edge analog-to-digital converter (ADC) from Linear Technology, designed to deliver high-speed, high-fidelity data conversion for a wide range of applications. This 14-bit ADC operates at a sampling rate of up to 250Msps, making it an ideal solution for demanding signal processing tasks that require rapid and precise digitalization of analog signals.

Built using Linear Technology's advanced silicon design techniques, the LTC2249IUH achieves outstanding dynamic performance, including a 73dB Signal-to-Noise Ratio (SNR) and 85dB Spurious Free Dynamic Range (SFDR). This level of performance ensures that signals are captured with high accuracy and minimal distortion, which is crucial for applications such as medical imaging, telecommunications, and instrumentation.

The LTC2249IUH comes in a compact QFN-32 (5mm x 5mm) package, which is well-suited for space-constrained applications. It operates over a single 1.8V supply, with a power consumption of just 140mW at the full 250Msps rate, making it an energy-efficient choice for portable and battery-powered devices.

The device features a flexible digital interface that supports both CMOS and LVDS logic levels, allowing for easy integration with a variety of digital signal processors (DSPs) and field-programmable gate arrays (FPGAs). Additionally, the LTC2249IUH includes features such as an optional internal dithering for improved SFDR performance over a wide input frequency range and an out-of-range indicator signal for robust error detection and handling.

Linear Technology's commitment to quality and reliability is evident in the LTC2249IUH, which is designed to meet the stringent requirements of industrial and military-grade specifications. Whether you're developing high-speed data acquisition systems, communication infrastructure, or advanced radar and imaging technologies, the LTC2249IUH provides the performance and reliability you need to deliver superior results.
