DESCRIPTION

The ADC12081 is a monolithic CMOS analog-to-

digital 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 self- calibration 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.
