V, 18-Bit, Low-Power, Multichannel, Oversampling Sigma-Delta ADC

General Description The MAX1400 18-bit, low-power, multichannel, serial output 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
