A data converter (10) and a method for attenuating noise in an output signal generated by the data converter (10). The data converter (10) includes a sigma-delta modulator (16), a digital-to-analog converter (17), a clock generator (19) connected to the digital-to-analog converter (17), and a clock control circuit (18) connected to the clock generator (19). The clock control circuit (18) enables or disables the clock generator (19) in accordance with the single-bit digital signal to cause a notch characteristic in the output signal for attenuating noise in the output signal. |
