ADC12L030/ADC12L032/ADC12L034/ADC12L038 3.3V Self-Calibrating 12-Bit Plus Sign Serial I/O A/D Converters with MUX and Sample/Hold June 1999 ADC12L030/ADC12L032/ADC12L034/ADC12L038 3.3V Self-Calibrating 12-Bit Plus Sign Serial I/O A/D Converters with MUX and Sample/Hold General Description The ADC12L030 family is 12-bit plus sign successive approximation A/D converters 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 vari...
