ADC12041
12-Bit Plus Sign 216 kHz Sampling Analog-to-Digital
Converter
General Description
Operating from a single 5V power supply, theADC12041 is a
12 bit + 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-calibration process that adjusts linearity, zero and
full-scale errors.
TheADC12041 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.
