Maxim Integrated MAX1400

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 rate. The device achieves true 16-bit performance at an output data rate of up to 480sps.

GENERAL DESCRIPTION

In addition, the modulator sampling frequency may be optimized for either lowest power dissipation or highest throughput rate. The MAX1400 operates from +5V. This device offers three fully differential input channels that can be independently programmed with a gain between +1V/V and +128V/V. Furthermore, it can compensate an input-referred DC offset (such as system 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. External access is provided to the multiplexer (mux) output to facilitate additional signal processing. The MAX1400 can be configured to scan all signal inputs sequentially and provide the results through the serial interface with minimum communications overhead. When used with a 2.4576MHz or 1.024MHz master clock, the digital deci...
