Monolitich CMOS ADC provides excellent dynamic performance

Texas Instruments ADC12010 12-Bit ADC is a monolithic CMOS ADC able to convert analog input signals into 12-bit digital words at 10MSPS, minimum. This converter utilises a differential, pipeline architecture with digital error correction and an on-chip sample-and-hold circuit to reduce die size and power consumption while giving an excellent dynamic performance. Running on a single 5V power supply, this device uses just 160mW at 10MSPS, including the reference current. The Power Down feature lessens power consumption to 25mW. The differential inputs provide a full-scale input swing equal to 2VREF with the opportunity of a single-ended input. Full use of the differential input is suggested for optimum performance. For ease of use, high impedance, the buffered, single-ended reference input is converted on-chip to a differential reference for use by the processing circuitry. Output data format is 12-bit offset binary. Typical applications include image processing front end, PC-based data acquisition, wireless local loops/cable modems, waveform digitizers, and DSP front ends.
