Product Summary

The ADC10154CIWM is a CMOS 10-bit plus sign successive approximation A/D converter with versatile analog input 4-channel multiplexers, track/hold function and a 2.5V band-gap reference. The 4-channel multiplexers of ADC10154CIWM can be software configured for single-ended, differential or pseudo-differential modes of operation. The input track/hold of ADC10154CIWM is implemented using a capacitive array and sampled-data comparator. Resolution can be programmed to be 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. Application areas of the ADC10154CIWM include Process control, Instrumentation and Test equipment.
