ADC0844/ADC0848 8-Bit µP Compatible A/D Converters with Multiplexer Options June 1999 ADC0844/ADC0848 8-Bit µP Compatible A/D Converters with Multiplexer Options General Description The ADC0844 and ADC0848 are CMOS 8-bit successive approximation A/D converters with versatile analog input multiplexers. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential or pseudo-differential modes of operation. The differential mode provides low frequency input common mode rejection and allows offsetting the analog range of the converter. In addition, the A/D’s reference can be adjusted enabling the conversion of reduced analog ranges with 8-bit resolution. The A/Ds are designed to operate from the control bus of a wide variety of microprocessors.
