MAX1402 - +5V / 18-Bit / Low-Power / Multichannel / Oversampling Sigma-Delta ADC

General Description

The MAX1402 low-power, multichannel, serial-output analog-to-digital converter (ADC)

Key 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 dissipation or highest throughput rate. T.
