MAX1400CAI+

The MAX1400CAI+ is a +5V, 18bit, low-power, multichannel, oversampling (sigma-delta) ADC in 28 pin SSOP package. This ADC uses a sigma-delta modulator with a digital decimation filter to achieve true 16bit accuracy at an output data rate of 480sps. The user-selectable decimation factor of the digital filter allows the conversion resolution to be reduced in exchange for a higher output data rate. The modulator sampling frequency may be optimized for either lowest power dissipation or highest throughput rate. The MAX1403 operates from +5V. It offers three fully differential input channels that may be independently programmed with a gain between +1V/V and +128V/V. It can compensate an input-referred DC offset up to 117% of the selected full-scale range. These three differential channels may also be configured to operate as five pseudo differential input channels. Two additional, fully differential system-calibration channels are provided for gain and offset error correction.

• Supply voltage range is 4.75V to 5.25V
