MAX1400 Datasheet (Maxim) - Oversampling (Sigma-Delta) ADC

MAX1400, Oversampling (Sigma-Delta) ADC

The MAX1400 18-bit, low-power, multichannel, serialoutput ADC uses a sigma-delta modulator with a digital decimation filter to achieve true 16-bit accuracy.

The user-selectable decimation factor of the digital filter allows the conversion resolution to be reduced in exchange for a higher output data
