ADC12048 - 12-Bit Plus Sign 216 kHz 8-Channel Sampling Analog-to-Digital Converter

General Description

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.

ADC12048 12-Bit Plus Sign 216 kHz 8-Channel Sampling Analog-to-Digital Converter April 2000 ADC12048 12-Bit Plus Sign 216 kHz 8-Channel Sampling Analog-to-Digital Converter General Description 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.
