The ADC12281 is a monolithic CMOS analog-to-digital converter capable of converting analog input signals into 12-bit digital words at 20 megasamples per second (MSPS). It utilizes a pipeline architecture to minimize die size and power dissipation. Self-calibration and error correction maintain accuracy and performance over temperature.

The ADC12281 operates on a 5V power supply and can digitize single-ended analog input signals in the range of 0V to 2V. A single convert clock controls the conversion operation and all digital I/O is TTL compatible.

The ADC12881 is designed to minimize external components necessary for the analog input interface. An internal sample-and-hold circuit samples the single-ended analog input and an internal amplifier buffers the reference voltage input.

The Power Down feature reduces power consumption to 20 mW, typical.

The ADC12281 is available in the 32-lead TQFP package and is designed to operate over the industrial temperature range of -40°C to +85°C.
