AD7828KNZ

AD7828KNZ Description

The AD7828KNZ from Analog Devices Inc. is an 8-bit, flash architecture analog-to-digital converter (ADC) designed for high-speed, low-power data acquisition systems. Housed in a 28-pin DIP package, it features 8 single-ended inputs, a 50kSPS sampling rate, and operates on a 5V analog/digital supply, making it suitable for industrial and embedded applications. The device employs an external reference voltage, ensuring flexibility in precision requirements. Its parallel data interface enables straightforward integration with microcontrollers and digital systems. With a 1:1 sample-and-hold (S/H) to ADC ratio, the AD7828KNZ delivers consistent performance in dynamic signal environments.

AD7828KNZ Features

• 8-bit resolution with flash conversion for rapid response times.
• 8-channel single-ended input multiplexer for versatile signal handling.
• 50k samples per second (50kSPS) throughput for real-time data acquisition.
• 5V single-supply operation (analog and digital), simplifying power design.
• External reference voltage support for adjustable accuracy.
• Parallel interface for seamless communication with processors.
• Wide operating temperature range (0°C to 70°C) for industrial environments.
• ROHS3 compliant and REACH unaffected, meeting environmental standards.
• Through-hole mounting (DIP) for robust prototyping and production.

AD7828KNZ Applications

The AD7828KNZ excels in applications requiring moderate resolution with high-speed conversion, such as:

• Industrial control systems (PLC I/O modules, sensor interfaces).
