The AD7628KR is a low power, 16-bit, single-channel, digital-to-analog (DAC) converter designed for use in data acquisition systems. It is capable of providing up to ±10V output range with a resolution of 0.5mV. The ADC is optimized for single-supply operation with a supply voltage range of 2.7V to 5.5V. The converter technology used in the design of the AD7628KR is analog-to-digital conversion (ADC) technology, which is also referred to as a delta-sigma converter.

AD7628KR converter includes on-chip reference and an output amplifier, making it an ideal solution for applications that require a high dynamic range (DNR) and strong signal to noise ratio (SNR). The DAC features analog performance of 16-bits resolution and ±10V output range. The device supports full scale output with a resolution of 0.5 mV, enabling accurate control and precision measurement of analog signals. The AD7628KR also has software and hardware error correction capabilities to minimize errors in the DAC output.

The AD7628KR is designed with a proprietary sigma-delta technology that offers low noise and low distortion at high data rates. The converter is capable of operating at data rates up to 1.6 MSPS, making it suitable for applications such as communications, test and measurement and consumer electronics. The output amplifier of the AD7628KR offers a gain of 1.1V/V, which is able to supply up to ±10V of output range with a full-scale resolution of 0.5 mV. The device also offers an adjustable output range, allowing users to tailor the output to their application requirements. Furthermore, the device supports "safe input" protection with an optional inhibit (INH) feature, allowing the user to safely program input codes into the DAC without resulting in any undesirable analog output levels. The AD7628KR also features power-up and down sequencing options, which allows the terminal user to safely power up or down the DAC.

The device also employs an on-chip internal reference, providing stability and accuracy for the DAC output. The integrated reference is capable of providing output voltage across the single power supply range of 2.7V to 5.5V. Additionally, the reference is programmable for fine-tuning ADC and DAC output parameters. Moreover, the AD7628KR also includes on-chip oscillators and sample-and-hold (S/H) circuitry which enable synchronization of DAC operation with other data acquisition systems.

In summary, the AD7628KR is a 16-bit, single-channel digital-to-analog (DAC) converter designed for data acquisition systems. It offers a wide range of features including 16-bit resolution and ±10V output range, integrated reference and S/H circuitry, adjustable output range and power-up/down sequencing options, making it an ideal solution for various applications.
