The AD7224KRZ-18REEL is a 12-bit, high-speed, low-power, unbuffered voltage output digital-to-analog converter (DAC) from the Analog Devices family of products. This device is a great choice for many different applications and can be used in various systems with the help of its extended features. In order to understand how the DAC can be used, one must understand its application field and working principle.

Application Field

The AD7224KRZ-18REEL DAC is specifically designed for use in high performance data acquisition systems, especially in low-voltage industrial applications. This 12-bit DAC can be used for tasks such as controlling motor drives, manufacturing processes, robot servos, building automation systems, and equipment such as test and measurement instruments. This DAC can also find applications in aerospace, defense and scientific research as well as consumer and medical applications.

Due to its extremely low power consumption, the DAC is an ideal solution for embedded systems which require low power consumption and an industry-leading combination of speed, resolution, and accuracy. The device operates from a single 3.3 V supply and is designed to fit into the small footprint of a standard 18-pin package.

Working Principle

The AD7224KRZ-18REEL DAC operates on the principle of voltage output, where the device converts 12-bits of digital input into an analog signal of up to 10V. This conversion is accomplished through a series of digital comparators that compare each bit of digital data to a set of analog reference signals. When a given comparison is successful, the digital input is converted to an analog signal which is then output from the DAC.

The device supports digital input formats of 2’s complement, BCD, Gray-code, offset binary and binary, and the output is available in both differential and single-ended configurations. The output impedance of the DAC is extremely low and the settling time is rapid. The device also features a power-down mode to save power when not actively in use, and operates over an extended operating temperature range (-25°C to 105°C).

Conclusion

The AD7224KRZ-18REEL DAC is a great choice for many different data acquisition and motor control applications, offering an industry-leading combination of speed, resolution, and accuracy. This 12-bit DAC operates from a single 3.3 V power supply, supports several digital input formats, and can output up to 10V. In addition, the device features an extremely low power consumption and an extended temperature operating range making it an ideal choice for embedded systems.
