General Description
The MAX1403 18-bit, low-power, multichannel, serial-
output analog-to-digital converter (ADC) features
matched 200A 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 user-selectable decimation factor allows the con-
version 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. The MAX1403 operates from +3V.
This device offers three fully differential input channels
that may be independently programmed with a gain
between +1V/V and +128V/V. Furthermore, it can com-
pensate an input-referred DC offset up to 117% of the
selected full-scale range. These three differential chan-
nels 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.
The MAX1403 can be configured to sequentially scan all
signal inputs and provide the results via the serial inter-
face with minimum communications overhead. When
used with a 2.4576MHz or 1.024MHz master clock, the
digital decimation filter can be programmed to produce
zeros in its frequency response at the line frequency and
associated harmonics, ensuring excellent line rejection
without the need for further postfiltering.
The MAX1403 is available in a 28-pin SSOP package.
