Product Overview: AD7247ATQ from Analog Devices Inc.

The AD7247ATQ is a state-of-the-art dual 12-bit digital-to-analog converter (DAC) designed by Analog Devices Inc., a leader in high-performance semiconductors. This precision DAC is part of the AD7247 series, known for its high-speed and accurate data conversion capabilities. The product is ideal for a wide range of applications, including industrial control systems, automated test equipment, and digital signal processing.

Featuring an on-chip output amplifier, the AD7247ATQ provides a voltage output that is directly proportional to the digital word input, with the capability of settling within 1 LSB in 1 µs. The DAC operates from a single +12 V to +15 V supply or from dual ±12 V to ±15 V supplies, offering flexibility in system design. The device also incorporates an advanced thin-film on CMOS technology to ensure high reliability and performance.

Each of the two DACs on the AD7247ATQ chip has its own voltage reference input, allowing for independent operation and providing the user with the ability to set different output ranges for each DAC. This feature is particularly useful in systems that require multiple voltage levels to be generated simultaneously.

The device's digital interface is TTL/CMOS compatible, ensuring easy integration with a variety of microprocessors and digital systems. With a 12-bit parallel data input format, the AD7247ATQ can communicate quickly and efficiently with the rest of the system, minimizing data transfer times and enhancing overall system throughput.

The AD7247ATQ is packaged in a 24-lead ceramic DIP (dual in-line package), which provides robust physical protection and ensures reliable operation even in harsh environmental conditions. Additionally, the product is specified over the extended industrial temperature range of -40°C to +85°C, making it suitable for outdoor and rugged applications.

In summary, the AD7247ATQ from Analog Devices Inc. is a versatile and high-performance dual DAC solution that offers excellent accuracy, fast settling times, and a flexible interface for a wide range of applications. Its robust design and temperature resilience make it a top choice for engineers and designers looking for reliable data conversion in their systems.
