ADC12048
12-Bit Plus Sign 216 kHz 8-Channel Sampling
Analog-to-Digital Converter
General Description
Operating from a single 5V power supply, theADC12048 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
self-calibration process that adjusts linearity, zero and
full-scale errors.
TheADC12048’s 8-channel multiplexer is software program-
mable
to
operate
in
a
variety
single-ended, differential, or pseudo-differential modes. The
fully differential MUX and the 12-bit + signADC allows for the
difference between two signals to be digitized.
TheADC12048 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.
