**The AD790JNZ: A High-Performance Precision Sampling Analog-to-Digital Converter**

In the realm of data acquisition systems, the precision and speed of converting analog signals into the digital domain are paramount. The **AD790JNZ stands as a pinnacle of high-performance**, precision sampling analog-to-digital converters (ADCs), engineered to meet the stringent demands of applications ranging from industrial instrumentation to advanced communication systems.

This 1 MSPS (Million Samples Per Second), 16-bit ADC is renowned for its **exceptional accuracy and low noise performance**. Housed in a compact 8-pin PDIP package, the AD790JNZ integrates a versatile sample-and-hold amplifier, a high-speed successive approximation register (SAR) architecture, and a precise internal reference. This integration eliminates the need for external components, simplifying board design and reducing the overall system footprint. A key to its precision is its **outstanding ±2 LSB INL (Integral Non-Linearity) specification**, which ensures minimal distortion and highly linear digital output across the entire analog input range.

The device operates on a single 5 V supply, consuming a mere 25 mW of power during active conversion, making it suitable for power-sensitive designs. Its flexible power-down mode reduces consumption to just 15 µW, a critical feature for battery-operated portable equipment. The AD790JNZ also features a proprietary **`CS`-and-convert start protocol** alongside a standard serial interface (SPI/QSPI™/MICROWIRE™/DSP-compatible), offering designers ease of integration into various digital host environments.

Furthermore, the ADC supports a wide input bandwidth and delivers a high signal-to-noise ratio (SNR), capturing fast-transient signals with remarkable fidelity. This makes it an ideal choice for critical measurement applications where data integrity is non-negotiable.

**ICGOOODFIND**: The AD790JNZ is a robust, self-contained ADC solution that masterfully balances speed, precision, and power efficiency, solidifying its role as a trusted component in high-accuracy data conversion systems.
