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, respec-
tively. 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,
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 ob-
tained 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 MI-
CROWIRE
. For voltage references, see the LM4040 or
LM4041.
