**LTC1857CG#TRPBF: A High-Performance 16-Bit, 8-Channel Simultaneous Sampling Data Acquisition System**

In the realm of precision data acquisition, the ability to capture multiple sensor readings at the exact same instant is critical for applications requiring high accuracy and phase coherence. The **LTC1857CG#TRPBF** from Analog Devices stands out as a premier solution, integrating a **16-bit, 8-channel simultaneous sampling data acquisition system** into a single, robust package. This device is engineered to deliver exceptional performance where timing alignment between channels is paramount.

The core of the LTC1857's functionality is its **eight synchronous sampling track-and-holds**. Unlike multiplexed ADCs that sequentially sample channels, introducing skew, this device samples all eight inputs simultaneously. This feature is indispensable for multi-phase power monitoring, polyphase motor control, instrumentation, and vibration analysis, where the precise phase relationship between signals must be preserved for accurate system analysis and control.

Driving this capability is a high-speed, **16-bit successive approximation register (SAR) analog-to-digital converter (ADC)**. It ensures high linearity and low noise, achieving outstanding **AC accuracy and DC performance**. The device supports a flexible input range, configurable for ±10V or 0V to 5V operation per channel, making it versatile for interfacing with a wide array of sensors and signal conditioning circuits without external level-shifting components.

Communication with a system controller is streamlined through a high-speed parallel interface, facilitating rapid data transfer. Furthermore, the LTC1857 is designed for ease of integration, requiring minimal external components. Its operation is optimized for low power consumption, a key attribute for portable or high-channel-count systems.

Housed in a compact 48-lead SSOP package, the **LTC1857CG#TRPBF** offers a powerful combination of high channel count, simultaneous sampling, and 16-bit resolution. It effectively eliminates the timing errors inherent in multiplexed systems, providing designers with a reliable and accurate solution for the most demanding measurement challenges.

**ICGOOODFIND:** The LTC1857CG#TRPBF is an integrated **simultaneous sampling ADC** that provides **exceptional phase coherence** across eight channels. Its high 16-bit resolution and flexible input ranges make it an ideal, all-in-one solution for complex, multi-channel data acquisition systems where **precise timing and high accuracy** are non-negotiable requirements.
