A Digital to Analog Converter (DAC) is a device used to convert a digital representation of an analog signal into an analog signal. DAC082S085CISDX/NOPB is one of the many types of digital-to-analog converter and is ideally suited for industrial/commercial/automotive applications.

Application Field

The DAC082S085CISDX/NOPB is a versatile, cost-effective and high-speed 8-bit, 3.3-V DAC with integrated amplifier that is ideal for a wide variety of applications, including industrial/commercial/automotive operations. It is widely used to improve efficiency and accuracy in applications such as servo or torque control, frequency/phase control, instrumentation, transaction terminals and test and measurement.

The DAC082S085CISDX/NOPB offers high linearity with an output full-scale error of 8-bit and low temperature coefficient of full-scale error (FSR error). The DAC082S085CISDX/NOPB is optimized to deliver the maximum full-scale output voltage over temperature and across the extended operating supply range (from 2.7 V to 5.5 V). Moreover, the device provides fast settling time (10 μs) and fast slew rate (5 V/μs).

The DAC082S085CISDX/NOPB can also be used in applications requiring low power with three power-saving measures – a low supply voltage (2.7 V to 5.5 V), a high-efficiency amplifier and a low-power bypass input feature. With these features, the DAC082S085CISDX/NOPB can significantly reduce system power consumption without sacrificing performance.

.This device also offers different configurations which allow the user to select the ideal setup or mixture of features, thereby helping to streamline designs. The user can also program a variety of features, such as gain and offset adjustment, via a 3-wire serial bus. Further customization using SPI command codes.

Working Principle

DAC082S085CISDX/NOPB works on the principle of Digital-to-Analog conversion. A Digital-to-Analog Converter (DAC) is a device which converts a digital signal into an analog signal. It accomplishes this by taking digital data values as inputs and generating an analog equivalent of the same data as output. The DAC082S085CISDX/NOPB has an 8-bit input, three-wire serial interface, and a three-state analog output with an integrated amplifier. This device is used most commonly in industrial/commercial/automotive applications.

The device uses a ladder-type design technique with a series of resistors and capacitors. Each 8-bit input word is connected to a different segment in the resistor network and the output is regulated according to the input word. When the input word is all zeros, the output is zero, while when the input word is all ones, the output is full-scale. This design is known as a voltage-output or segmented-type DAC.

The DAC082S085CISDX/NOPB also uses a digital filter to reduce the nonlinearities of the DAC output over the 8-bit range. The user can also program offset and gain adjustment, allowing the user to select the ideal setup or mixture of features, thereby helping to streamline designs.

The DAC082S085CISDX/NOPB offers low power consumption, fast settling time (10 μs) and fast slew rate (5 V/μs), making it highly suitable for industrial/commercial/automotive applications. It is also cost-effective and able to deliver a maximum full-scale output voltage over temperature across an extended operating supply range (2.7 V to 5.5 V). The device is suitable for a wide range of voltage control and stabilization systems such as those in servo or torque control, frequency/phase control, instrumentation and test and measurement applications.
