●NOTE: Some of these devices may be obsolete and are described and shown here for reference only. See our web site for product availability.

●The ADC12030, and ADC12H030 families are 12-bit plus sign successive approximation Analog-to-Digital Converters with serial I/O and configurable input multiplexers. The ADC12034/ADC12H034 and ADC12038/ADC12H038 have 4 and 8 channel multiplexers, respectively. The differential multiplexer 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 multiplexer outputs and ADC inputs internally connected. The ADC12030 family is tested with a 5 MHz clock, while the ADC12H030 family is tested with an 8 MHz clock. On request, these ADCs go through a self calibration process that adjusts linearity, zero and full-scale errors to less than ±1 LSB each.

●The analog inputs can be configured to operate in various combinations of single-ended, differential, or pseudo-differential modes. 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 even when the negative inputs are greater than the positive because of the 12-bit plus sign output data format.

●The serial I/O is configured to comply with NSC MICROWIRE. For voltage references see the LM4040, LM4050 or LM4041.
