Description

Operating from a single 5V power supply, the ADC12041 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.
The ADC12041 can be configured to work with many popular microprocessors/microcontrollers and DSPs including National's HPC family, Intel386 and 8051, TMS320C25, Motorola MC68HC11/16, Hitachi 64180 and Analog Devices ADSP21xx.
