**LTC2358ILX-16#PBF: A 16-Bit, 8-Channel Simultaneous Sampling SAR ADC for High-Performance Data Acquisition Systems**

In the realm of high-performance data acquisition, the ability to accurately capture multiple sensor readings at the same precise instant is paramount. The **LTC2358ILX-16#PBF** from Analog Devices stands as a premier solution, engineered to meet the rigorous demands of applications such as power line monitoring, multi-axis motion control, phased-array sonar, and industrial instrumentation.

This integrated circuit is a **16-bit, 8-channel simultaneous sampling SAR ADC**. Its core architecture is built around a single successive approximation register (SAR) analog-to-digital converter, which is multiplexed across eight individual sample-and-hold amplifiers. This design is critical, as it allows all eight channels to acquire their analog inputs at the exact same moment, **preserving the critical phase relationship between channels**. The subsequent conversions are then processed sequentially, outputting a stream of data where the digital values for each channel are correlated to that single snapshot in time.

The performance specifications of the LTC2358ILX-16#PBF are exceptional. It achieves **outstanding AC performance**, including a high signal-to-noise ratio (SNR) and low total harmonic distortion (THD), ensuring that even the most subtle signals are digitized with clarity and precision. Its flexible operation is another key strength; it supports a wide range of input spans (±10.24V, ±5.12V, ±2.56V, 0V to 10.24V) that can be individually programmed for each channel via the serial interface. This allows designers to interface directly with different sensor types without requiring additional signal conditioning circuitry. Furthermore, the device features a robust **SPI-compatible serial interface** that simplifies communication with modern microcontrollers, FPGAs, and DSPs.

The benefits of using this ADC extend beyond its raw specifications. By integrating eight channels into a single 64-lead LQFP package, it significantly reduces board space, component count, and system complexity compared to using multiple discrete ADCs. This integration leads to a more reliable and cost-effective design. The device's high level of integration and performance makes it an indispensable component for systems where **simultaneous, high-fidelity measurement of multiple analog signals** is non-negotiable.
