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.
