Data Acquisition - Digital to Analog Converters (DAC) are core components of many today\'s digital systems, allowing them to convert digital data into analog signals. Such devices take a binary digital signal as an input and convert it into a proportional analog signal, outputting voltages in direct relations to digital values. Manufactured by Analog Devices, Inc., Model DAC7724NB/750G4 belongs to the family of 14-bit, 4-channel, voltage output precision Digital to Analog Converters, and provide a great performance in low- to mid-range applications.

DAC7724NB/750G4 Application Areas

The DAC7724NB/750G4 can be used in various applications, both in improvement and replacement of existing, outdated equipment. It particularly excels in motor and actuator control, production and process control, home, and building automation, test and measurement equipment, temperature control, analog data acquisition, and many other. The device can be used in the majority of the areas where an accurately-controlled voltage is required.

DAC7724NB/750G4 Operating Principle

The working principle of the DAC7724NB/750G4 lies in its architechture. The device is designed on a series of cascaded unipolar voltage-controlled switches. These are controlled and driven by processed digital data, which are usually sent in binary form on the multiplexed serial interface. Each switch is set to hold a voltage and is connected to 20 resistor segments and 16 switches in each channel. This allows for fine-grain control of the output voltage, which is proportional to the digital input. Thus, upon conversion, several equivalent and scaled output voltages are produced.

Once the voltage is applied, it is held in capacitors located just below the switches. The capacitors have an active voltage divider, which ensures uniform charge distribution even when output currents as high as 1.2mA are drawn. This is compensated for by the auto-calibration circuitry, ensuring accurate behavior of the device in all operating conditions.

DAC7724NB/750G4 Design Considerations

The DAC7724NB/750G4 has several notable design considerations, most of which creating a significant advantage over other devices in its class. It boasts a 14-bit resolution, allowing it to achieve 16 million discrete voltage levels with little jitter. The device can operate on a single +15V power supply while providing a voltage range of 0-10V. It also supports direct data processing and scaling with the use of the integrated DAC AutoCalibration feature. Furthermore, the DAC7724NB/750G4 is built using Enhanced Band Gap (EBG) technology for fewer errors, and has an extremely low INL and DNL. However, the output independent of input and the guaranteed 14-bit performance have made the device particularly popular.

Conclusion

The DAC7724NB/750G4 is an ideal choice for applications where precise voltage control is needed. Its integrated AutoCalibration circuitry provides accurate operation of the device, while its 14-bit resolution, low error rate, and scalability in a small package makes it very attractive for use. As such, the device is most appropriate for use in motor and actuator control, production and process control, home and building automation, test and measurement equipment, temperature control, and data acquisition areas.
