ADC12048

12-Bit Plus Sign 216 kHz 8-Channel Sampling

Analog-to-Digital Converter

General Description

Operating from a single 5V power supply, the ADC12048 is a

12 bit + sign, parallel I/O, self-calibrating, sampling

analog-to-digital converter (ADC) with an eight input fully dif-

ferential analog multiplexer. The maximum sampling rate is

216 kHz.

On

request,

the

ADC

goes

through

a

self-calibration process that adjusts linearity, zero and

full-scale errors.

The ADC12048’s 8-channel multiplexer is software program-

mable

to

operate

in

a

variety

of

combinations

of

single-ended, differential, or pseudo-differential modes. The

fully differential MUX and the 12-bit + sign ADC allows for the

difference between two signals to be digitized.

The ADC12048 can be configured to work with many popular

microprocessors/microcontrollers and DSPs including Na-

tional’s HPC family, Intel386 and 8051, TMS320C25, Mo-

torola MC68HC11/16, Hitachi 64180 and Analog Devices

ADSP21xx.

For complementary voltage references see the LM4040,

LM4041 or LM9140.
