The ADC10154 and ADC10158 are CMOS 10-bit plus sign successive approximation A/D converters with versatile analog input multiplexers, track/hold function and a 2.5V band-gap reference. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential or pseudo-differential modes of operation.
The input track/hold is implemented using a capacitive array and sampled-data comparator.
Resolution can be programmed to be 8-bit, 8-bit plus sign, 10-bit or 10-bit plus sign. Lower-resolution conversions can be performed faster.
The variable resolution output data word is read in two bytes, and can be formatted left justified or right justified, high byte first.
