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 differential 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 programmable 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 Tl's HPC family, Intel386 and 8051, TMS320C25, Motorola MC68HC11/16, Hitachi 64180 and Analog Devices ADSP21xx.
