Working Principle

The DAC8565IDPWG4 is a low-power, low-noise, and high-precision digital-to-analog converter. It is capable of producing an analog output signal from a digital input signal. The DAC8565IDPWG4 uses a current-output converter type architecture and a nonlinear DAC core to convert a digital signal into an analog output signal. This process is accomplished by way of a charge redistribution technique with an on-chip resistive voltage divider, which is connected to the output buffer to provide gain and offset adjustment.The current-output type architecture reduces the power consumption of the converter compared to a voltage-output type architecture. The voltage output is obtained by current sensing, which requires a resistor between the output and the buffer. The resistor acts as a damper, limiting the effect of the voltage on the output of the buffer.The DAC8565IDPWG4 also features an on-chip digital interpolation and decimation filter. The filter reduces spurious noise and improves output accuracy. The interpolation and decimation filter can be configure to operate at different speeds and different frequency responses.
