AD669ARZ-REEL is a 16-bit low cost voltage output digital to analog converter (DAC) which features an on-board reference and small packages. The output of the DAC is bipolar, with a programmable full-scale output range from ±10V to ±2.5V. The actual full-scale output of the converter can be set independently from the internal reference of ±2.5V. The DAC also features true 16-bit linearity, making it suitable for high accuracy applications.

The AD669ARZ-REEL most popular application is for applications where a wide output range and high accuracy is needed, such as laboratory instrumentation, audio, telecommunications, and process control. Due to its 16-bit accuracy and wide output range, this DAC is also well suited for medical and industrial process control systems. Additionally, its low cost and small packages make it especially attractive for cost sensitive applications.

The working principle of the AD669ARZ-REEL is that it converts digital data into analog electrical voltages. The conversion is accomplished by encoding a digital word into the analog output range. The conversion is done by a successive approximation register (SAR), which is a type of analog-to-digital (ADC) circuit. The SAR works by performing a binary search through the digital word, and a gain multiplier to increase the resolution. The DAC takes the digital word and converts it into an analog voltage.

The output of the DAC is controlled by the digital word and the internal reference voltage. The full-scale output range of the DAC is set by adjusting the reference voltage. The accuracy of the DAC is also determined by the level of the internal reference voltage. The reference voltage must be accurately set for the DAC to perform its best.

In conclusion, the AD669ARZ-REEL is a 16-bit low cost voltage output digital to analog converter (DAC) which features an on-board reference and small packages. It is well suited for applications where a wide output range and high accuracy is needed, such as laboratory instrumentation, audio, telecommunications, and process control. The working principle of the DAC is that it converts digital values into analog electrical voltages. It uses a SAR circuit and a gain multiplier to achieve the desired resolution and range of output. The accuracy of the DAC is determined by the level of the internal reference voltage. The reference voltage must be accurately set for the DAC to perform its best.
