Update: 29 September, 2023
The ADC12L030 family is a 12-bit plus sign successive approximation A/D converter with serial I/O and configurable input multiplexers. These devices are fully tested with a single 3.3V power supply. The ADC12L032, ADC12L034 and ADC12L038 have 2, 4 and 8 channel multiplexers, respectively. Differential multiplexer outputs and A/D inputs are available on the MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2 pins. The ADC12L030 has a two channel multiplexer with the multiplexer outputs and A/D inputs internally connected. On request, these A/Ds go through a self calibration process that adjusts linearity, zero and full-scale errors to less than ±1⁄2 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 +3.3V) can be accommodated with a single +3.3V 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 two’s compliment output data format. The serial I/O is configured to comply with NSC’s MICROWIRE™ and Motorola’s SPI standards. For voltage references, see the LM4040 or LM4041 data sheets.
