Working Principle

The DAC7724UB/1K employs an 8-bit digital-to-analog converter, 8-bit digital input multiplexer, and octal reference placed on the same die to provide high accuracy conversions with a maximum conversion rate of 1K samples/second. When a digital logic signal is applied to the 8-bit digital input of the device, the digital data is converted to an analog output. The conversion is done by a two-step process. First, the digital input data is multiplexed by the 8 bit digital multiplexer and then multiplied with a reference voltage by the 8 bit DAC. The reference voltage is digitally adjustable and can be adjusted over a wide range of values. The digital input data can be applied serially or in parallel.

The output of the DAC7724UB/1K is a high-impedance analog voltage and has a typical full-scale voltage range of 0 to +5 V. The output voltage can be converted to a 0 to 20 mA current with an external resistor. The output voltage can be adjusted by the 8-bit resolution, which also offers improved accuracy and performance. The device is also low-noise and can be used in noise-sensitive applications such as medical instrumentation.

Conclusion

The DAC7724UB/1K is an ultra-low-power and high-performance data acquisition device specifically designed for bridging the gap between analog and digital applications. It combines an 8-bit digital-to-analog converter and 8-bit digital input multiplexer with an octal reference, providing maximum accuracy and performance in a small form factor package. This is an ideal device for applications such as medical instrumentation, voltage regulation and control loop applications, where power consumption is critical and performance is required.
