19-1423; Rev 2; 1/07 EVAALVUAAILTAIOBNLEKIT +5V, 18-Bit, Low-Power, Multichannel, Oversampling (Sigma-Delta) ADC General Description The MAX1402 low-power, multichannel, serial-output analog-to-digital converter (ADC) Features matched 200µA current sources for sensor excitation. This ADC uses a sigma-delta modulator with a digital decimation filter to achieve 16-bit accuracy. The digital filter’s userselectable decimation factor allows the conversion resolution to be reduced in exchange for a higher output data rate. True 16-bit performance is achieved at an output data rate of up to 480sps. In addition, the modulator sampling frequency may be optimized for either lowest power...
