ADC12138 Datasheet PDF - National

General Description

●The ADC12130, ADC12132 and ADC12138 are 12-bit plus sign successive approximation A/D converters with serial I/O and configurable input multiplexer. The ADC12132 and ADC12138 have a 2 and an 8 channel multiplexer, respectively. The differential multiplexer outputs and A/D inputs are available on the MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2 pins. The ADC12130 has a two channel multiplexer with the multiplexer outputs and A/D inputs internally connected. The ADC12130 family is tested with a 5 MHz clock. On request, these A/Ds go through a self calibration process that adjusts

●linearity, zero and full-scale errors to typically less than ±1 LSB each.
