The ADC12030, and ADC12H030 families are 12-bit plus signsuccessive approximation Analog-to-Digital Converters withserial I/O and configurable input multiplexers. TheADC12034/ADC12H034 and ADC12038/ADC12H038 have4 and 8 channel multiplexers, respectively. The differentialmultiplexer outputs and ADC inputs are available on the MUXOUT1,MUXOUT2, A/DIN1 and A/DIN2 pins. The ADC12030/ADC12H030 has a two channel multiplexer with the multiplexeroutputs and ADC inputs internally connected. TheADC12030 family is tested with a 5 MHz clock, while the ADC12H030family is tested with an 8 MHz clock. On request,these ADCs go through a self calibration process that adjustslinearity, zero and full-scale errors to less than ±1 LSB each.The analog inputs can be configured to operate in variouscombinations of single-ended, differential, or pseudo-differentialmodes. A fully differential unipolar analog input range(0V to +5V) can be accommodated with a single +5V supply.In the differential modes, valid outputs are obtained evenwhen the negative inputs are greater than the positive becauseof the 12-bit plus sign output data format.
