Overview

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 July 1999 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, respectively.
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 multiplexer 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, 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.
Features Serial I/O (MICROWIRE Compatible) 2, 4, or 8 channel differential or single-ended multiplexer Analog input sample/hold function Power down mode Variable resolution and conversion rate Programmable acquisition time Variable digital output word length and format No zero or full scale adjustment required Fully tested and guaranteed with a 4.
