A sigma delta modulator (100) includes a first circuit (102, 104, 106, 108, 110, 112, 114, 116, 118) that receives an analog signal and provides an intermediate signal and a first quantizer signal and further includes a first quantizer (120) that receives the first quantizer signal and provides a first quantizer output. Also included are a second input circuit (128, 130, 132, 134, 136, 138, 140, 144, 146) that receives the intermediate signal and provides a second quantizer signal and a second quantizer (142) that receives the second quantizer signal and provides a second quantizer output. The first quantizer includes a programmable circuit (204, 208) having a first reference and a negative of the first reference, a first comparator (206) having a first input coupled to the first quantizer signal, a second input coupled to the first reference and a second comparator (210) having a second input coupled to the first quantizer signal a second input coupled to the negative. The first and second comparators have outputs that form the output of the first quantizer.
