3.3V Self-Calibrating 12-Bit Plus Sign Serial I/O A/D
Converters with MUX and Sample/Hold
General Description
The ADC12L030 family is 12-bit plus sign successive ap-
proximation A/D converters with serial I/O and configurable
input multiplexers. These devices are fully tested with a
single 3.3V power supply. TheADC12L032,ADC12L034 and
ADC12L038 have 2, 4 and 8 channel multiplexers, respec-
tively. Differential multiplexer outputs and A/D inputs are
available on the MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2
pins. TheADC12L030 has a two channel multiplexer with the
multiplexer outputs and A/D inputs internally connected. On
request, these A/Ds go through a self calibration process
that adjusts linearity, zero and full-scale errors to less than
±
1
2
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 +3.3V) can be accommodated with a
single +3.3V 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 two’s compliment
output data format.
The serial I/O is configured to comply with NSC’s
MICROWIRE
and Motorola’s SPI standards. For voltage
references, see the LM4040 or LM4041 data sheets.
