**LTC2358CLX-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 analog signals at the same precise instant is paramount. The **LTC2358CLX-16#PBF** from Analog Devices stands as a pinnacle component in this domain, integrating an 8-channel multiplexer with a **high-speed, low-power successive approximation register (SAR)** analog-to-digital converter (ADC). This combination delivers exceptional performance for complex systems in industrial automation, power quality monitoring, and advanced instrumentation.

The core feature of this ADC is its **simultaneous sampling capability**. All eight channels can sample their respective input voltages at the same moment, triggered by a single CONVST command. This is critical in polyphase systems and any application where the phase relationship between multiple signals must be preserved for precise analysis, such as in motor control, vibration analysis, or seismic recording. The device then sequentially converts each sampled value, outputting the results through a high-speed SPI-compatible serial interface.

Performance is underpinned by its **16-bit resolution**, ensuring fine granularity and dynamic range. It achieves a remarkable throughput of up to **1Msps per channel**, making it suitable for capturing fast-transient events. Furthermore, the LTC2358CLX-16#PBF excels in its **outstanding AC performance** (e.g., low THD and high SINAD) and excellent DC accuracy (with low offset and gain error), which are essential for demanding measurement scenarios.

Designed for versatility, it supports a wide ±4.096V input range per channel, allowing it to handle bipolar signals directly. Its robust design includes internal buffers, which simplify front-end driving requirements. Operating from a single 5V supply and consuming only 24mW per channel at maximum speed, it offers an excellent balance of speed and power efficiency, a crucial factor in multi-channel systems where power dissipation can be a challenge.

**ICGOOFind:** The LTC2358CLX-16#PBF is an exceptional solution for engineers designing high-channel-count data acquisition systems where **simultaneous sampling**, high accuracy, and robust performance are non-negotiable. Its integration of eight channels with high-speed 16-bit conversion simplifies system design, reduces component count, and provides the fidelity required for the most demanding measurement applications.
