The AD7228KN is an advanced, high resolution, digital-to-analog converter (DAC) suitable for a variety of industrial and consumer applications. It provides a highly accurate and low drift performance thanks to the use of state-of-the-art, eight-bit multi-level digital-to-analog converter (MIDAC) circuitry. The DAC takes a single-ended input and produces an output voltage with eight different voltage levels per sample. This makes it perfect for applications in which precise, repeatable voltage levels are required.

The AD7228KN application range extends from audio, including equalization and loudness control, to precision voltage amplification and measurement. Additionally, it is ideal for applications in medical imaging, automotive, industrial power control, and consumer electronics. These application areas benefit from the AD7228KN’s low power consumption, low offset voltage, low noise, and grounded offset pin.

The AD7228KN’s working principle involves the conversion of an input digital signal into an output analog voltage. The module employs an internal 8-bit digital-to-analog converter (DAC), an internal reference voltage for reference voltage, an eight-level voltage ladder, and a low-pass filter for output low-frequency noise rejection. The module accepts an 8-bit digital word and converts it into one of the eight possible output voltage levels, which are determined by the reference voltage. The output voltage is generated at the output of the low-pass filter, which helps reduce the noise of the converted analog signal.

The AD7228KN is a versatile and cost-effective solution for applications that require precise control of output voltage levels. The precision 8-bit DAC and on-chip low-pass filter ensure the highest levels of accuracy and repeatability, while the low power consumption and low noise make it ideal for use in battery-operated and noisy environments. The module is also designed for low EMI and can be used in a variety of different applications without interfering with other nearby devices. The AD7228KN is an ideal solution for data acquisition, precision voltage measurement and control, audio equalization and loudness control, and medical imaging.
