Overview

ADC12130/ADC12132/ADC12138 Self-Calibrating 12-Bit Plus Sign Serial I/O A/D Converters with MUX and Sample/Hold March 2000 ADC12130/ADC12132/ADC12138 Self-Calibrating 12-Bit Plus Sign Serial I/O A/D Converters with MUX and Sample/Hold 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.
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 the NSC MICROWIRE™.
For voltage references, see the LM4040 or LM4041.
