1 / 17 page ADC12081 12-Bit, 5 MHz Self-Calibrating, Pipelined A/D Converter with Internal Sample & Hold General Description The ADC12081 is a monolithic CMOS analog-to-digital con- verter capable of converting analog input signals into 12-bit digital words at 5 megasamples per second (MSPS). The ADC12081 utilizes an innovative pipeline architecture to minimize die size and power consumption. The ADC12081 uses self-calibration and error correction to maintain accu- racy and performance over temperature. The ADC12081 converter operates on a 5V power supply and can digitize analog input signals in the range of 0 to 2V. A single convert clock controls the conversion operation. All digital I/O is TTL compatible. The ADC12081 is designed to minimize external compo- nents necessary for the analog input interface. An internal sample-and-hold circuit samples the analog input and an internal amplifier buffers the reference voltage input. The ADC12081 is available in the 32-lead LQFP package and is designed to operate over the extended commercial temperature range of -40˚C to +85˚C.
