ADC12H030/ADC12H032/ADC12H034/ADC12H038,
ADC12030/ADC12032/ADC12034/ADC12038
Self-Calibrating 12-Bit Plus Sign Serial I/O A/D
Converters with MUX and Sample/Hold
General Description
The ADC12030, and ADC12H030 families are 12-bit plus
sign successive approximation A/D converters with serial I/O
and
configurable
input
multiplexers.
The
ADC12032/
ADC12H032,
ADC12034/ADC12H034
and
ADC12038/
ADC12H038 have 2, 4 and 8 channel multiplexers, respec-
tively. The differential multiplexer outputs and A/D inputs are
available on the MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2
pins. The ADC12030/ADC12H030 has a two channel multi-
plexer with the multiplexer outputs and A/D inputs internally
connected. The ADC12030 family is tested with a 5 MHz
clock, while the ADC12H030 family is tested with an 8 MHz
clock. On request, these A/Ds go through a self calibration
process that adjusts linearity, zero and full-scale errors to
less than
±
1 LSB each.
The analog inputs can be configured to operate in various
combinations
of
single-ended,
differential,
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.
