Data Acquisition - Digital to Analog Converters (DAC) have become increasingly important in an ever-expanding digital world. The AD5668SRU-EP-1 is a high-performance, low-cost 8-bit DAC designed to interface to microcontrollers and digital signal controllers (DSC) for the analog conversion of digital signals.

The AD5668SRU-EP-1 provides a reliable platform for outputting an analog signal using digital input data. Its 8-bit resolution offers accuracy and resolution at an excellent value. The AD5668SRU-EP-1 features a differential output voltage range of 0.6 V to 4.0 V combined with a complementary analogue output, further boosting the performance.

The AD5668SRU-EP-1 includes a 2.5 V reference Voltage for improved accuracy and stability, as well as an offset adjustment circuit and temperature compensation feature for added system stability. The differential output, low voltage and supply voltage are separately adjustable, allowing designers to configure the output signal.

The AD5668SRU-EP-1 digital-to-analog converter has extensive applications in medical devices, data acquisition systems and industrial instrumentation. In medical systems, it is used for biological signal acquisition, such as electrocardiogram acquisition, neural signal acquisition and tissue-pressure signals. In data acquisition systems, it is used to monitor various physical parameters such as voltage, current, temperature, humidity and pressure. In industrial instruments, it is used to measure process temperature, pressure, flow rate, and other physical parameters. The accurate and efficient results delivered by the AD5668SRU-EP-1 can in turn be utilised to monitor, control and maintain industrial parameters.

The working principle of the AD5668SRU-EP-1 operates based on the principle of voltage conversion. The input digital data is converted into an analogue output voltage in the form of offset binary codes. This is achieved by means of an internal voltage divider section and a set of 11 digital-to-analogue converters (DACs). Power is supplied using a single +3.3V supply, while an externally provided reference voltage is used to scale and shift the output voltage range. The digital input data can be written using the I2C bus protocol, while the SDA, SCL and SYNC pins are used to configure the DAC.

In equipment that requires precise and accurate analog outputs, the AD5668SRU-EP-1 digital-to-analog converter proves to be a suitable solution. Its 8-bit resolution and differential output voltage feature combined with its low cost makes it an ideal choice for a variety of data acquisition applications.
