摘要：
A digital to analog converter for converting a digital input signal provided by a host to an analog output signal includes a modulator receiving the digital input signal, modulating the digital input signal, and outputting a modulated signal, and a filtering circuit receiving the modulated signal, low pass filtering the modulated signal, and outputting the analog output signal to an output node. The filtering circuit includes a first switching circuit for adjusting the bandwidth of the filtering circuit according to a bandwidth switching signal.
