**LTC1855CG#PBF: A 16-Bit, 8-Channel Simultaneous Sampling Data Acquisition System**

In the realm of precision measurement and data acquisition, the ability to accurately capture multiple analog signals at the same instant is paramount. The **LTC1855CG#PBF** from Analog Devices represents a pinnacle of integration and performance, engineered to meet the demanding requirements of high-speed, multi-channel systems. This device is a **16-bit, 8-channel simultaneous sampling** data acquisition system that combines high resolution with exceptional functionality, making it an ideal solution for complex applications such as power quality monitoring, phased-array sonar, and multi-axis motion control.

At the heart of the LTC1855 is its **simultaneous sampling capability**. Unlike multiplexed ADCs that sequentially sample each channel, introducing skew between measurements, this IC samples all eight input channels at precisely the same moment. This is achieved through eight individual sample-and-hold amplifiers, each dedicated to its respective input. This feature is critical for applications where the **phase relationship between signals** is essential for accurate analysis, such as in calculating power in multi-phase systems or performing vibration analysis on machinery.

The **16-bit resolution** ensures that the digitized data is both highly detailed and accurate. With a **maximum throughput of 100kSPS per channel**, the converter provides ample speed for a wide range of industrial and instrumentation tasks. The device offers flexible input ranges, including ±10V and 0V to 5V, which can be selected on a per-channel basis, providing significant versatility in interfacing with various sensors and signal conditioning circuits.

Integration is a key strength of the LTC1855. It includes an internal high-speed parallel interface and an onboard reference, simplifying design and reducing the bill of materials. The **low power consumption** and single +5V supply operation make it suitable for portable or space-constrained applications. Furthermore, its robust design ensures reliable operation in electrically noisy environments.

**ICGOOODFIND**: The LTC1855CG#PBF is a highly integrated, precision data acquisition solution that eliminates channel-to-channel timing skew. Its combination of simultaneous sampling, high resolution, and multi-channel integration makes it a superior choice for designers building advanced measurement and control systems.
