Data Acquisition - Digital to Analog Converters (DAC) play an important role in many electronic devices and systems. Examples of the technology can be found in audio and video equipment, medical instruments, digital-to-analog converters, telecommunications, industrial applications and so on. One of the most widely used DACs is DAC7611PBG4, which is designed to provide audio- and video-analog-output performance of high quality.

The DAC7611PBG4 is a high-precision 12-bit voltage-output Digital To Analog converter. The device preserves the full resolution of the converter during warm- and cold-start conditions. The DAC7611PBG4 is available in SOIC and PDIP packages and is fully specified for the 3V and 5V systems. The DAC7611PBG4 is designed to address the specific needs of two primary application fields: low-bandwidth general-purpose and high-bandwidth audio. In general purpose use, the DAC7611PBG4 provides the throughput of 12-bit resolution and 12-bit precision in the voltage range of 0 to 5 V.

However, in audio applications, the device provides the throughput of 12-bit resolution and 16-bit precision in the voltage range of 0 to 10 V. The DAC7611PBG4 is equipped with programmable current and voltage offsets in order to cover a variety of operating conditions. It also features three operating-mode selectors for the noise-shaping, dithering and offset current levels, as well as programmable power-supply and output-voltage ranges. All these features guarantee perfect operation performance in wide range of applications.

The DAC7611PBG4 employs a voltage-output architecture, which ensures the lowest noise operation and offers the highest signal accuracy. This device uses the R-2R resistor-ladder technology that promises wonderful performance in conversion accuracy and linearity. The R-2R technology enables the DAC7611PBG4 to achieve the accuracy given in the PID diagram, so the final analog output will be very close to the ideal value. This means that it provides high precision voltage output, with low power consumption, making the DAC7611PBG4 an ideal choice for high-bandwidth audio applications.

The R-2R ladders for the DAC7611PBG4 provide the performance of 16-bit accuracy in every cycle. This device has also a robust power-supply rejection ratio of 72 dB, which limits the power-supply noise from the DAC7611PBN4. Additionally, the DAC7611PBG4 features three shutdown modes, enabling the user to select the most suitable mode for the particular application. Finally, the DAC7611PBG4 is fully protected against ESD and is available in 100 nF and 1 nF packages.

In conclusion, the DAC7611PBG4 is a high-precision 12-bit voltage-output Digital-to-Analog converter designed to address the specific needs of two primary application fields: low-bandwidth general-purpose and high-bandwidth audio. This device has the low noise and power consumption, wide operating range, high accuracy and linearity, robust protection against ESD. The DAC7611PBG4 is a great choice for any application field, as it can provide audio and video analog output of high quality.
