Analog-to-Digital Converter
General Description
Operating from a single 5V power supply the ADC12041 is a
12 bit a sign parallel I O self-calibrating sampling analog-
to-digital converter (ADC) The maximum sampling rate is
216 kHz On request the ADC goes through a self-calibra-
tion process that adjusts linearity zero and full-scale errors
The ADC12041 can be configured to work with many popu-
lar microprocessors microcontrollers including National’s
HPC family
Intel386 and 8051 TMS320C25 Motorola
MC68HC11 16 Hitachi 64180 and Analog Devices
ADSP21xx
