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 witha5MHz

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,

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 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.
