ADC12L030/ADC12L032/ADC12L034/ADC12L038

3.3V Self-Calibrating 12-Bit Plus Sign Serial I/O A/D

Converters with MUX and Sample/Hold

General Description

Features

n 0V to 3.3V analog input range with single 3.3V supply

n Serial I/O ( MICROWIRE and SPI Compatible)

n 2 or 8 channel differential or single-ended multiplexer

n Power down mode

NOTE: These products are now obsolete.

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. The ADC12L032, ADC12L034 and

ADC12L038 have 2, 4 and 8 channel multiplexers, respec-

tively. Differential multiplexer outputs and A/D inputs are

available at the MUXOUT1, MUXOUT2, A/DIN1 and A/DIN2

pins. The ADC12L030 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

n Programmable acquisition time

n Variable digital output word length and format

n No zero or full scale adjustment required

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 +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.

40 µW (typ)

Applications

n Portable Medical instruments

n Portable computing

The serial I/O is configured to comply with NSC’s

MICROWIRE and Motorola’s SPI standards. For voltage

references, see the LM4040, LM4050 or LM4041 data

sheets.

The ADC12L032 and the ADC12L034 are not recommended

for new designs and are presented for reference only.
