**LTC2325HUKG-14#PBF: A 14-Bit, 5Msps, Low Noise SAR ADC for High Precision Data Acquisition Systems**

In the realm of high-performance data acquisition, the **LTC2325HUKG-14#PBF** from Analog Devices stands out as a superior 14-bit, 5Msps successive approximation register (SAR) analog-to-digital converter (ADC). Engineered for systems demanding uncompromising accuracy and speed, this ADC integrates **exceptional linearity** and **ultra-low noise performance** into a compact 40-lead QFN package, making it an ideal solution for a wide array of precision applications.

The core strength of the LTC2325HUKG-14#PBF lies in its **outstanding DC precision**. It boasts a typical ±0.5 LSB integral nonlinearity (INL) and ±0.3 LSB differential nonlinearity (DNL), ensuring minimal distortion and highly accurate digital representations of analog signals. This is further enhanced by its impressive **97dB signal-to-noise ratio (SNR)** at 100kHz input, which is remarkable for a SAR ADC at this sampling rate. This low noise floor is critical for resolving tiny signals in the presence of larger ones, a common requirement in scientific instrumentation, medical imaging, and high-end industrial control systems.

A key feature that simplifies system design is its **fully differential input range**, which provides excellent common-mode noise rejection. This is vital in electrically noisy environments where maintaining signal integrity is paramount. The device operates from a single 5V supply, simplifying power architecture, and features a **flexible serial peripheral interface (SPI)** for seamless communication with modern microcontrollers, FPGAs, and DSPs. Its high 5Msps throughput enables the capture of fast transient events, making it suitable for power quality analysis, sonar, and automated test equipment.

Furthermore, the LTC2325HUKG-14#PBF includes **internal reference and buffer**, reducing the bill of materials (BOM) and design complexity while ensuring stable performance. For applications requiring multiple synchronized channels, the ADC supports daisy-chain mode, allowing several devices to be connected and controlled with a single serial interface.

ICGOODFIND: The LTC2325HUKG-14#PBF is a high-performance 14-bit SAR ADC that delivers an optimal blend of **5Msps speed, exceptional linearity, and ultra-low noise**. Its integrated features and robust interface make it a premier choice for designers building next-generation high-precision data acquisition systems.
