**LTC1864IS8#TRPBF: A 16-Bit, 250ksps, Single-Channel SAR ADC in MSOP-8 Package**

The **LTC1864IS8#TRPBF** from Analog Devices represents a highly integrated, precision analog-to-digital converter (ADC) designed for applications demanding high resolution and compact form factor. This device is a **16-bit, successive approximation register (SAR) ADC** capable of sampling at speeds up to **250k samples per second (ksps)**. Housed in an **MSOP-8 package**, it exemplifies how advanced performance can be achieved within a minimal footprint, making it an ideal solution for space-constrained and portable instrumentation.

A key strength of the LTC1864 lies in its simplicity and efficiency. As a **single-channel** ADC, it is optimized for dedicated signal acquisition tasks, eliminating the complexity and potential error sources associated with internal multiplexers. Its SAR architecture provides deterministic latency and rapid response, which is critical for control loops and other real-time systems. The ADC operates from a single **2.7V to 5.5V supply**, enhancing its versatility for both 3V and 5V systems, and features a flexible serial interface that is easily compatible with most modern microcontrollers (MCUs) and digital signal processors (DSPs).

The performance metrics of the LTC1864 are impressive. It delivers **true 16-bit resolution** with no missing codes, ensuring high accuracy in measurement. With a typical integral nonlinearity (INL) of ±2.5 LSB and signal-to-noise ratio (SNR) of 89dB, it provides excellent dynamic performance for precise data acquisition. Furthermore, it incorporates a high-accuracy internal oscillator, requiring no external components for its operation, which simplifies design and reduces the overall bill of materials (BOM).

Typical applications are found in environments where size, power, and accuracy are paramount. These include **portable medical devices**, industrial process control, battery-operated equipment, and high-accuracy sensor interfaces. Its small MSOP-8 package is particularly advantageous in these fields, allowing designers to maintain a high signal-to-noise ratio while minimizing the PCB area.

**ICGOOFind**：The LTC1864IS8#TRPBF stands out as a superior choice for designers seeking a compact, high-resolution, and single-channel ADC. Its combination of **16-bit accuracy**, **250ksps speed**, and an **ultra-small MSOP-8 package** offers a compelling solution for modern, miniaturized electronic systems that cannot compromise on performance.
