Data Acquisition - Digital to Analog Converters (DAC)

Digital to Analog Converters (DAC) are devices that convert digital measurements into analog form, providing a bridge between the digital and analog environment. The AD9114BCPZRL7 is a 4-channel, 16-bit, 500MSPS, voltage-output DAC. It is designed for applications that require low power and high performance in a low-cost, very small footprint.

Applications

The AD9114BCPZRL7 is a versatile converter and can be used in a wide range of applications. It is suitable for high-speed sampling and data acquisition systems, digital signal processing, telecommunications and avionics systems, software-defined radio, medical imaging, digital X-ray, RADAR and sonar systems, automotive and consumer testing, instrumentation, and more.

Features

The AD9114BCPZRL7 is designed to be low power and high performance. Features include a 16-bit resolution, 5 GHz Nyquist bandwidth, sampling rates up to 500MSPS, voltage swing up to 4V, excellent linearity and noise performance, and glitch impulse unaffected by the system clock.

Design

The AD9114BCPZRL7 is powered by a single 5V supply and is available in a 28-pin LQFP package, giving it a very small form factor. The device is fully compatible with LVDS and CMOS standards, and features include a programmable voltage reference, built-in single-ended and differential offset cancellation, and a low-jitter clock multiplier.

Working Principle

The AD9114BCPZRL7 is a voltage-output DAC, which means that the digital input is converted to an analog voltage level at the output. The digital input is first converted to a 1-bit binary pattern, which is then converted to an analog voltage output through a conversion process. The AD9114BCPZRL7 is designed to convert digital signals at speeds of up to 500MSPS and a resolution of 16 bits.The device features an offset cancellation circuit which uses a combination of passive components and active circuitry, including an amplifier and summing circuit, to cancel out any offsets the device might have. This ensures the presence of an accurate output voltage corresponding to the desired digital input. In addition, the AD9114BCPZRL7 is designed to maintain excellent performance across a wide range of temperatures, as well as high linearity, excellent noise performance, and glitch impulse free from system clock. This helps to ensure that the device can be used in a wide range of applications where accuracy and reliability is essential.

Conclusion

The AD9114BCPZRL7 is an ideal choice for applications that require low power and high performance in a low-cost, very small package. With a 16-bit resolution and excellent linearity and noise performance, the device can be used in a wide range of applications such as high-speed data acquisition systems, software-defined radio, medical imaging, digital X-ray and more.
