**LTC1867CGN#PBF: A 16-Bit, 250ksps, 8-Channel Sampling ADC for High-Accuracy Data Acquisition Systems**

In the realm of precision measurement and control, the ability to accurately convert analog signals into digital data is paramount. The **LTC1867CGN#PBF** from Analog Devices stands out as a premier solution, engineered to meet the rigorous demands of high-accuracy data acquisition systems. This integrated circuit is a **16-bit, 8-channel, 250ksps successive approximation register (SAR) analog-to-digital converter (ADC)** that combines exceptional performance with versatile functionality.

The core of the LTC1867's appeal lies in its **exceptional 16-bit resolution**, which ensures that even the most minute analog signals are captured with high fidelity. This is crucial for applications where precision is non-negotiable, such as medical instrumentation, seismic monitoring, and advanced industrial process control. The device achieves a **high sampling rate of 250k samples per second**, enabling it to accurately digitize dynamic signals without missing critical transient details. This speed is perfectly suited for multi-channel systems that require rapid cycling through inputs.

A key feature of this ADC is its **integrated 8-channel multiplexer**. This allows a single converter to sequentially sample up to eight different analog input signals, significantly reducing the component count, board space, and system cost compared to using multiple single-channel ADCs. The multiplexer can be configured for either single-ended or differential input modes, providing design flexibility to handle a wide range of sensor outputs and improve noise immunity in electrically noisy environments.

The LTC1867 is designed for ease of integration and robust performance. It operates from a single **5V supply** and features a versatile **SPI-compatible serial interface**, simplifying communication with most modern microcontrollers and digital signal processors (DSPs). Its internal high-performance sample-and-hold circuit guarantees accurate sampling even at the maximum throughput. Furthermore, the device is available in the **SSOP-24 package**, offering a compact footprint for space-constrained applications while ensuring reliable operation across the industrial temperature range.

**ICGOO**DFIND: The LTC1867CGN#PBF is a highly integrated and precise data conversion solution, offering **outstanding accuracy, multi-channel flexibility, and a compact form factor**, making it an ideal choice for sophisticated data acquisition systems.
