Abstract

A sigma-delta analog-to-digital converter (ADC) is disclosed. The sigma delta ADC has an analog input and a digital output. A sigma-delta modulator input is coupled to the analog input and a sigma-delta modulator output. A first filter having a first filter input is coupled to the sigma-delta modulator output and a first filter output. A second filter having a second filter input is coupled to the sigma-delta modulator output and a second filter output. The sigma-delta ADC operates in a first and second mode. In a first mode, the first filter output is coupled to the digital output. In a second mode, the second filter output is coupled to the digital output.
