ADC12191
12-Bit, 10 MHz Self-Calibrating, Pipelined A/D Converter
with Internal Sample & Hold
General Description
The ADC12191 is a monolithic CMOS analog-to-digital con-
verter capable of converting analog input signals into 12-bit
digital words at 10 megasamples per second (MSPS). The
ADC12191 utilizes an innovative pipeline architecture to
minimize die size and power consumption. The ADC12191
uses self-calibration and error correction to maintain accu-
racy and performance over temperature.
The ADC12191 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 ADC12191 is designed to minimize external compo-
nents necessary for the analog input interface. An internal
sample-and-hold circuit samples the analog input and an in-
ternal amplifier buffers the reference voltage input.
The ADC12191 is available in the 32-lead TQFP package
and is designed to operate over the extended commercial
temperature range of -40C to +85C.
