**The AD7674ACPZ: A 16-Bit, 250 kSPS PulSAR® ADC for High-Precision Data Acquisition Systems**

In the realm of high-precision data acquisition, the resolution, speed, and accuracy of an analog-to-digital converter (ADC) are paramount. The **AD7674ACPZ from Analog Devices** stands out as a premier 16-bit, 250 kSPS successive approximation register (SAR) ADC, engineered to meet the stringent demands of precision measurement systems. Leveraging the proprietary **PulSAR® architecture**, this ADC delivers exceptional performance in applications ranging from industrial automation and scientific instrumentation to medical imaging and seismic monitoring.

At the core of the AD7674ACPZ is its **16-bit resolution**, ensuring fine granularity in digitizing analog signals. With a sampling rate of **250 kilosamples per second (kSPS)**, it adeptly captures dynamic signals without compromising detail. The device incorporates a high-performance, low-noise sampling circuitry that minimizes distortion and preserves signal integrity. Its **integrated precision reference and buffer** reduce external component count, simplifying design while enhancing system reliability. The ADC supports both bipolar and unipolar input ranges, offering flexibility for diverse sensor interfaces.

One of the standout features is its **low power consumption**, typically drawing 100 mW during operation, making it suitable for power-sensitive applications. The AD7674ACPZ also boasts **excellent linearity**, with typical INL (Integral Non-Linearity) of ±0.6 LSB and DNL (Differential Non-Linearity) of ±0.4 LSB, ensuring accurate conversion across the entire input range. The serial interface (SPI/QSPI™ compatible) facilitates easy connection to modern microcontrollers and DSPs, while its 10 MHz interface speed enables rapid data transfer.

Housed in a compact **32-lead LFCSP (Lead Frame Chip Scale Package)**, the ADC is designed for space-constrained environments. Its robust design includes **high immunity to noise and interference**, critical in electrically noisy industrial settings. Whether used in data loggers, spectrum analyzers, or automated test equipment, the AD7674ACPZ provides the precision and speed needed for critical measurements.

**ICGOODFIND:** The AD7674ACPZ is a top-tier 16-bit SAR ADC that combines high resolution, **exceptional accuracy**, and **moderate speed** with low power consumption, making it an ideal choice for **demanding data acquisition systems** where precision is non-negotiable.
