ADC12081 www.ti.com SNAS020D – MARCH 2000 – REVISED MARCH 2013 ADC12081 12-Bit, 5 MHz Self-Calibrating, Pipelined A/D Converter with Internal Sample & Hold Check for Samples: ADC12081 FEATURES 1 2 Single 5V Power Supply Simple Analog Input Interface Internal Sample-and-Hold Internal Reference Buffer Amplifier Low Power Consumption APPLICATIONS Image Processing Front End PC-Based Data Acquisition Scanners Fax Machines Waveform Digitizer DESCRIPTION The ADC12081 is a monolithic CMOS analog-todigital converter 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 selfcalibration and error correction to maintain accuracy 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 components 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.
