**LTC2323IUFD-16#PBF: A 16-Bit, 5Msps, 8-Channel Simultaneous Sampling SAR ADC for High-Accuracy Data Acquisition Systems**
In the realm of high-precision data acquisition, the ability to accurately capture multiple analog signals simultaneously is paramount. The **LTC2323IUFD-16#PBF** from Analog Devices stands out as a premier solution, engineered to meet the rigorous demands of advanced industrial, scientific, and test and measurement applications. This 16-bit, 5Msps, 8-channel simultaneous sampling SAR ADC integrates exceptional performance, high channel density, and robust functionality into a single package.
**Uncompromising Performance and Precision**
At the core of the LTC2323 is a successive approximation register (SAR) architecture renowned for its deterministic behavior and high accuracy. With a **16-bit resolution** and no missing codes, it ensures that even the most minute signal variations are captured with integrity. The device achieves an outstanding **signal-to-noise ratio (SNR) of 93dB** and a spurious-free dynamic range (SFDR) of 100dB typical, providing the clarity and dynamic range necessary for discerning subtle details in complex waveforms. Its low distortion performance is critical for applications like vibration analysis, power quality monitoring, and multi-axis motion control.
**True Simultaneous Sampling Across Eight Channels**
A defining feature of this ADC is its **eight fully-differential input channels**, each equipped with a dedicated sample-and-hold amplifier. This architecture guarantees that all input signals are sampled at the exact same instant, eliminating timing skew between channels. This capability is indispensable in polyphase systems, such as three-phase power conversion and motor control, where precise phase relationship measurements are crucial for system efficiency and stability.
**High-Speed Interface and Ease of Use**
Operating at a maximum throughput of **5 million samples per second (Msps)** per channel, the LTC2323 delivers both speed and precision. It features a versatile serial peripheral interface (SPI) that facilitates easy communication with a wide range of microcontrollers, FPGAs, and DSPs. The digital interface is designed for daisy-chaining multiple devices, simplifying the design of systems requiring even higher channel counts. Housed in a compact 7mm x 7mm 48-lead QFN package, it offers a superb balance of performance and board space efficiency.
**Robustness for Demanding Environments**
Designed for reliability, the LTC2323 supports a wide analog input range of ±VREF, with a flexible reference voltage up to 5V, enabling a large ±5V input swing for high-voltage signals. It also incorporates robust features such as **internal oversampling** for improved noise performance and electromagnetic interference (EMI) hardening, ensuring consistent operation in electrically noisy environments.
**ICGOOODFIND Summary**
The LTC2323IUFD-16#PBF is a high-performance, highly integrated ADC that sets a benchmark for multi-channel data acquisition systems. Its combination of **true simultaneous sampling**, **excellent DC and AC accuracy**, **high channel density**, and **robust design** makes it an ideal choice for engineers developing the next generation of high-accuracy measurement and control systems.
