ADC12130/ADC12132/ADC12138

Self-Calibrating 12-Bit Plus Sign Serial I/O A/D

Converters with MUX and Sample/Hold

General Description

NOTE: All versions of the ADC12132 are obsolete and

shown here for reference only.

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 and specified 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, 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The ADC12132 is obsolete and described in this document

for reference only.

The serial I/O is configured to comply with NSC MICROW-

IRE™. For voltage references, see the LM4040, LM4050 or

LM4041.
