ADC12181 General Description
The ADC12181 is a monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 10 megasamples per second (MSPS). The ADC12181 utilizes an innovative pipeline architecture to minimize die size and power consumption. Self-calibration and error correction maintain accuracy and performance over temperature.
The ADC12181 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 ADC12181 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 ADC12181 is available in the 32-lead TQFP package and is designed to operate over the extended commercial temperature range of -40 to +85.
